Weekly Knowledge 80 Bangalore Ashram 19 Dec 1996  India THE FIVE ASPECTS OF THE UNIVERSE You have five aspects to yourself: Asti (is-ness); Bhaati (Knowledge, expression); Preeti (love); Nama (name); and Rupa (form). Matter has two aspects: name and form. Consciousness has three aspects: "is-ness" - that it is; knowingness/expression - it knows and expresses; and love - it is loving. This is the secret of the whole universe. Maya is not being aware of the three aspects of consciousness. Ignorance is when one is caught up in the name and form. Question: Why are we imperfect? Answer: So that we can grow to perfection. Life is a movement from imperfection to perfection. A seed contains the tree but the seed has to cease to be a seed to become a tree. The seed is not perfect. The sapling is not perfect. It has to cease to be a sapling to become a tree. So in life you can either see imperfection at every step, or you can see a movement from one perfection to another perfection. Wh...

Weekly Knowledge 81 Lake Lucerne 25 Dec 1996  Switzerland SURRENDER AND SELF-RELIANCE Self-reliance needs enormous courage. Surrender needs less courage. A person who cannot surrender cannot be self-reliant either. If you don't have enough courage to surrender, then it is impossible for you to be self-reliant. You simply fool yourself. People who are afraid to surrender fool themselves. Because even a little fear is detrimental to self-reliance. If you don't have a hundred dollars, you cannot have a thousand dollars. Self-reliance contains surrender. Fifty dollars contains ten dollars. Question: Why does self-reliance need so much courage? When you want to depend on yourself for everything, there is nobody else, then it needs a lot of courage. Often people think that surrender is a way to escape from responsibility and they end up blaming the Divine for all their problems. In fact, the true surrender is taking total responsibility for everything. Susannah: How can we do that? Y...

Weekly Knowledge 79 Bangalore Ashram 12 Dec 1996  India PLEASURE The mind that is seeking pleasure cannot be centered. You either seek pleasure or come to me. When you are centered, all pleasures come to you anyway, but they are no longer pleasures. They lose their charm. The mind that seeks pleasure can never achieve the highest. If you are after pleasure, forget about Satsang. Why are you wasting your time? This is the Art of Living. If you are enjoying your suffering, then you also cannot be centered and you are far away from the path. Susannah: What do you do when people talk negatively about this organization, Satsangs, teachers, or anybody for that matter? Guruji: From your side give license to everybody to talk about anything, about anybody, anywhere, at any time. Exercise -- Talk maximum negativity about everybody this whole week. This is a challenge. 🌸Jai Guru Dev🌸  साप्ताहिक ज्ञानपत्र ०७९ १२ दिसम्बर,१९९६ आश्रम, बंगलौर, भारत सुख वह मन जो सुख खोजता है, कभी भी केंद्रित नह...

Question - Gurudev, what is the importance of silence. How should we practice it? Gurudev Sri Sri - Take a moment, observe your breath, calm your mind, and relax your body. You find such peace and so much love within you. We are all born with this gift of love and peace. Somehow we forget to look within, which is of utmost importance. A few moments to introspection is very necessary. Either eyes open or closed, being in the moment, now, and relaxing suddenly connects you to yourself.

Question - Gurudev, the breath is so powerful. How does it work in connecting us to the subtle dimension? Gurudev Sri Sri - In the subtle you are already connected. The breath only makes you realise that you are connected. Your mind is always outside and it does not come back to itself, so the breath is the first step in bringing the outgoing mind inward. It is the doorway or the pathway, and meditation keeps the mind in the inner chamber.

Question - Gurudev, I have been very regular with my sadhana, seva and satsang for many years now. Despite this, I have been going through financial difficulties for the past three years and am very disturbed. Please advise. Gurudev Sri Sri - Everything will be alright in time. There may be some delay but it will surely happen. These difficulties will not last for long. See, the entire country is going through financial trouble. Our industrialists have been facing various financial difficulties for many years now. Our growth rate has fallen from 12% to -2.5%. What else can you expect when this happens? There will be financial troubles everywhere, people will suffer losses in business, these things will happen. But all this is going to change very soon. Have faith and patience.

Question - Gurudev, why is attaining spirituality necessary? Gurudev Sri Sri - It is because you want to be happy unconditionally, you want peace which does not get disturbed by small things. And this is quite natural. Wanting spirituality is as natural as wanting deep rest, as wanting to be loved, as wanting comfort and happiness. The definition of spirituality in Sanskrit is attaining greatest happiness, attaining greatest freedom (nirvana). It is natural. Like water flows down, and fire goes up, human beings want enlightenment.

Miami Beach, Florida United States 8th February, 1996 Chapter 1 - The You That You Want To Change Day 46 - Virtues Virtues cannot be cultivated. You must assume that they are there. In the Bhagavad Gita, Krishna said to Arjuna, “Grieve not Arjuna, you are born with virtues. “The seeker should remember that he is born with virtues, otherwise he would not be a seeker. If you think you have no virtues and then try to cultivate them, you will fail.  When you think you do not have a virtue, then you come from a space of lack or deficiency. You compare yourself with others on the basis of virtues. Do not compare yourself with anyone. Simply recognise all the virtues you appreciate in others and realise that those virtues are present in you in seed form.  You only have to nurture them. Virtues must be practiced until they become your nature. Friendliness, compassion and meditation should continue as practices until you realize that they are your very nature. The flaw in doing somethi...

Bangalore Ashram, India 17th September, 1998 Chapter 1 - The You That You Want To Change Day 47 - Sensitivity Those who are sensitive are often feel weak. Those who think themselves strong are often insensitive. Some are sensitive to themselves but insensitive to others. Some are sensitive to others but not to themselves. Those who are sensitive only to themselves often blame others.  Those who are only sensitive to others often end up feeling self pity. Some conclude it is better not to be sensitive at all because sensitivity brings pain, so they shut themselves off from others. But if you are not sensitive, you will lose all the finer things too intuition, beauty, and ecstasy of love. This path and this knowledge make you both sensitive and strong. Often people who are insensitive do not recognize their insensitivity and those who are sensitive often do not recognise sensitivity is their strength.  Sensitivity is intuition, sensitivity is compassion, sensitivity is love. Sen...

What is the circulatory system? Your heart and blood vessels make up the circulatory system. The main function of the circulatory system is to provide oxygen, nutrients and hormones to muscles, tissues and organs throughout your body. Another part of the circulatory system is to remove waste from cells and organs so your body can dispose of it. Your heart pumps blood to the body through a network of arteries and veins (blood vessels). Your circulatory system can also be defined as your cardiovascular system. Cardio means heart, and vascular refers to blood vessels. The circulatory system provides blood to all the body's tissues so they can function. What does the circulatory system do? The circulatory system’s function is to move blood throughout the body. This blood circulation keeps organs, muscles and tissues healthy and working to keep you alive. The ci...

Proteins Introduction ➖Proteins, which are basically biomolecules, play wide range of functions in the body of a living organism. ➖Proteins are made up of tiny elements of different types of amino acids. ➖A sequence of amino acid residues in a protein is known particularly by the sequence of a gene; gene is encoded in the genetic code. ➖After formation, proteins exist for a fixed period of time and are then degraded and recycled. ➖The proteins get recycled by the cell's machinery by the process of protein turnover. ➖Most of the proteins contain linear polymers made up of series of up to 20 different L-α-amino acids. ➖The amino acids in a polypeptide chain are connected by peptide bonds. ➖The peptide bond, usually, has two resonance forms, which contribute some double-bond characters. Protein Structure ➖Most of the proteins illustrate unique 3-dimensional structures. ➖However, proteins have not a rigid structure, but rather, proteins may vary between several related structures espec...

MUSCULAR SYSTEM:- • Muscle is a specialised tissue of mesodermal origin that has special properties like excitability, contractility,extensibility and elasticity.  Based on their location, three types of muscles are identified. Types of muscle:- Skeletal muscles:- These are closely associated with the skeletal components of the body. They have a striped appearance under the microscope and hence are called striated muscles. As their activities are under the voluntary control of the nervous system, they are known as voluntary muscles too. They are primarily involved in locomotory actions and changes of body postures. Visceral muscles:- These are located in the inner walls of hollow visceral organs of the body like the alimentary canal, reproductive tract, etc. They do not exhibit any striation and are smooth in appearance. Hence, they are called smooth muscles. They are not under the voluntary control of nervous system,hence are also called involuntary muscles. They assist, for examp...

Organ and their defects Organs are essential structures in the human body that perform specific functions necessary for survival and overall well-being. Each organ has a unique structure and function, and any defects or abnormalities in these organs can lead to various health conditions. One of the most well-known organs is the heart, as mentioned earlier. However, there are numerous other organs in the body, each with its own importance. Here are some examples: 1. Lungs: The lungs are responsible for the exchange of oxygen and carbon dioxide during breathing. Oxygen is taken in from the air and transported to the bloodstream, while carbon dioxide, a waste product, is expelled from the body. Lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), and lung cancer can impair this vital function. 2. Liver: The liver is the largest internal organ and performs several critical functions. It detoxifies harmful substances, produces bile for digestion, stores vitamins and m...

The human body is composed of several organ systems, each with its own specific functions and roles. Here is a brief overview of each organ system: 1. Integumentary System: The integumentary system consists of the skin, hair, nails, and various glands. It serves as a protective barrier against external factors, regulates body temperature, and helps in the synthesis of vitamin D. 2. Skeletal System: The skeletal system includes bones, cartilage, ligaments, and tendons. It provides support, protection, and movement for the body. Additionally, it produces blood cells and stores minerals such as calcium and phosphorus. 3. Muscular System: The muscular system is responsible for voluntary and involuntary movements of the body. It consists of skeletal muscles, smooth muscles, and cardiac muscles. 4. Nervous System: The nervous system controls and coordinates the activities of the body. It includes the brain, spinal cord, and peripheral nerves. The nervous system receives and processes sensory...

Neurophysiology  - Neurophysiology is the study of the functioning and activities of the nervous system. - It focuses on understanding how nerve cells (neurons) communicate with each other and how the brain and spinal cord process and transmit information. - The nervous system is composed of two main types of cells: neurons and glial cells. Neurons are responsible for transmitting electrical signals, while glial cells provide support and protection to neurons. - Neurons communicate through electrical impulses called action potentials. These impulses travel along the neuron's axon, which is covered by a myelin sheath that speeds up the transmission. - Synapses are the junctions between neurons where chemical signals, known as neurotransmitters, are released to transmit information from one neuron to another. - Neurotransmitters can have either excitatory or inhibitory effects on the receiving neuron, influencing whether it will generate an action potential or not. - The brain and sp...

Neuroscience is the study of the nervous system, which includes the brain, spinal cord, and peripheral nerves.  It is a multidisciplinary field that combines elements of biology, psychology, and chemistry to understand how the nervous system functions. The nervous system is responsible for controlling and coordinating all bodily functions. It receives information from the environment through sensory receptors and processes that information to produce appropriate responses. This can include actions such as movement, thoughts, emotions, and physiological changes. The nervous system is composed of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord, while the PNS includes all the nerves that extend from the CNS to the rest of the body. Neurons are the basic building blocks of the nervous system. These specialized cells transmit electrical signals, called action potentials, throughout the body to commun...

- The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials. - It consists of lymphatic vessels, lymph nodes, the spleen, thymus, and tonsils. - Lymphatic vessels are similar to blood vessels but carry a clear fluid called lymph instead of blood. - Lymph nodes are small, bean-shaped structures that filter lymph and contain immune cells that help fight infections. - The spleen is the largest lymphatic organ and filters blood, removing old or damaged red blood cells and storing platelets. - The thymus is located in the chest and plays a crucial role in the development and maturation of T-cells, which are important for immune response. - Tonsils are small masses of lymphoid tissue located in the back of the throat that help trap and filter bacteria and other pathogens. - The lymphatic system works in close coordination with the circulatory system to maintain fluid balance and defend against infections. - Lymph is formed f...

Bacteriology is a branch of microbiology that focuses on the study of bacteria.  Bacteria are single-celled microorganisms that can be found in various environments, including soil, water, and the human body. They are incredibly diverse and can have both beneficial and harmful effects on living organisms. The field of bacteriology encompasses several areas of study, including the classification and identification of bacteria, their growth and reproduction, their interactions with other organisms, and their role in causing diseases. Bacteriologists use various techniques and tools to study bacteria, such as microscopy, culturing methods, and genetic analysis. One of the key areas of interest in bacteriology is the role of bacteria in causing infectious diseases. Bacteria can invade the human body and cause a wide range of illnesses, from minor infections to life-threatening conditions. Understanding the mechanisms by which bacteria cause diseases is crucial for developing effective ...

Immunoglobulins, also known as antibodies,  are proteins produced by the immune system in response to the presence of foreign substances, such as bacteria or viruses. They are Y-shaped molecules that have two functional regions: the variable region, which recognizes and binds to specific antigens on pathogens, and the constant region, which mediates various immune responses. There are five main types of immunoglobulins: IgG, IgM, IgA, IgD, and IgE. Each type has a distinct structure and function in the immune response.  Immunoglobulin G (IgG) is the most abundant type in the body and provides long-term immunity against pathogens. It can neutralize toxins produced by bacteria and viruses, enhance phagocytosis (the engulfing and destruction of pathogens by immune cells), and activate complement proteins to destroy pathogens. Immunoglobulin M (IgM) is the first antibody produced during an initial immune response. It is effective at neutralizing pathogens and activating other comp...

Skin is the largest organ in the human body   and plays a vital role in protecting us from external threats. It acts as a barrier, shielding our internal organs from harmful substances, UV radiation, and pathogens. Moreover, skin also helps in regulating body temperature, maintaining hydration, and providing sensory information. The skin is composed of three layers: the epidermis, dermis, and hypodermis. The epidermis is the outermost layer and primarily functions as a protective shield. It consists of several layers of cells, including keratinocytes, which produce a tough protein called keratin that gives the skin its strength and flexibility. The epidermis also contains melanocytes, which produce melanin, the pigment responsible for skin color and protection against UV radiation. Beneath the epidermis lies the dermis, which is made up of connective tissue, blood vessels, hair follicles, sweat glands, and nerve endings. The dermis provides structural support to the skin and houses...

Mycology is the branch of biology that focuses on the study of fungi.  Fungi are a diverse group of organisms that include mushrooms, molds, and yeasts. They can be found in various habitats, such as soil, water, and even inside living organisms. Mycologists study various aspects of fungi, including their classification, identification, and ecology. They investigate the structure and function of fungal cells, their reproductive strategies, and their interactions with other organisms in their environment. Mycology also involves the study of fungal diseases in plants, animals, and humans. Fungi play important roles in ecosystems. They are decomposers, breaking down organic matter and recycling nutrients back into the environment. Fungi also form mutualistic relationships with other organisms, such as mycorrhizal associations with plant roots, where they provide nutrients to the plants in exchange for carbohydrates. In addition to their ecological significance, fungi have numerous pra...

Virology is a branch of microbiology that focuses on the study of viruses.  Viruses are microscopic infectious agents that can only replicate inside the cells of living organisms. They are much smaller than bacteria and can cause a wide range of diseases in humans, animals, and plants. The field of virology encompasses several areas of study, including the classification and identification of viruses, their structure and replication mechanisms, their interactions with host cells, and their role in causing diseases. Virologists use various techniques and tools to study viruses, such as electron microscopy, molecular biology techniques, and cell culture systems. One of the key areas of interest in virology is the understanding of viral pathogenesis. Viruses can enter host cells, hijack their machinery, and replicate, leading to the destruction of the infected cells and the spread of the virus throughout the body. Understanding the molecular mechanisms by which viruses cause diseases ...

The ear is a complex sensory organ that plays a vital role in our ability to hear and maintain balance.  It is divided into three main parts: the outer ear, middle ear, and inner ear. The outer ear consists of the visible part called the pinna or auricle, which helps collect sound waves and direct them into the ear canal. The ear canal is a narrow passage that leads to the eardrum, also known as the tympanic membrane. The middle ear is located behind the eardrum and contains three small bones called ossicles: the malleus (hammer), incus (anvil), and stapes (stirrup). These bones transmit sound vibrations from the eardrum to the inner ear. The middle ear also contains the Eustachian tube, which helps equalize air pressure between the middle ear and the environment. The inner ear is a complex structure located deep within the skull. It consists of the cochlea, responsible for hearing, and the vestibular system, responsible for balance. The cochlea is a spiral-shaped structure filled ...

Ophthalmology is a medical specialty that focuses on the diagnosis and treatment of diseases and disorders related to the eyes.  It involves the study of the anatomy, physiology, and diseases of the eyes and their surrounding structures. Ophthalmologists are medical doctors who specialize in ophthalmology. They are trained to provide comprehensive eye care, including conducting eye examinations, diagnosing and managing eye diseases, prescribing medications, performing surgeries, and providing vision correction treatments. The field of ophthalmology covers a wide range of conditions, including refractive errors (such as nearsightedness, farsightedness, and astigmatism), cataracts, glaucoma, macular degeneration, diabetic retinopathy, corneal diseases, eye infections, and many others. Ophthalmologists also play a crucial role in detecting and managing systemic diseases that can affect the eyes, such as diabetes and hypertension. Ophthalmology utilizes various diagnostic techniques an...

Nutrition is the science that studies the relationship between food and the human body,  including how nutrients are digested, absorbed, and utilized by the body for growth, development, and maintenance of health.
