Samadhi means equanimity

Chapter 3 - Samadhi 

Day 15 

What is the purpose of this sadhna? Vitarka - when your mind has a special logic to pursue in the world and to perceive the truth. Tarka means logic. Kutarka means wrong logic - when then intention is not right and the logic is applied only to find fault, when you know deep inside you that something is not right, but you still logically prove that it is right.

Vitarka is special logic. You may be talking about dispassion and logically you are understanding it, and this logical understanding, hearing or talking has a certain effect on your consciousness. It elevates your consciousness. You are in a different space. This is samadhi.

Samadhi means equanimity. "Dhi" is the intellect - the faculty that sustains you, faculty of consciousness. Now, we are in a state of Samadhi, because we are talking about the Self with a definite logic, an undeceivable logic. Logic can always change. You can put it on one side or you can put on the other. There is no loyalty. 

But Vitarka is a logic which cannot be condemned, which cannot be reversed. For example, if somebody is dead then it is obvious that he is dead. You know that the life that was there in the body is not there anymore. And that is the end. At that moment, your consciousness is in a different state. When you are not emotionally connected to anybody, what's happening to your consciousness? 

You feel that it is the end, for instance, when a movie is over, there is a feeling that all is over. When people walk out of the movie theatre, they are in a particular state of consciousness. They come out of a musical concert with a feeling that it is over. It is the same for a festival or for a course. When a course is over, the participants say that it has ended and they leave. 

The show is over. At that moment, there is a definite logic followed in the mind - irrefutable logic, irreversible logic that triggers your consciousness. It is so obvious.

Life is like this. It is so obvious. Everything is changing. They are bound to change, to dissolve and disappear. This vitarka elevates one's consciousness. One does not have to sit with the eyes closed or eyes open. 

The feeling of "I", the consciousness is all that is. Everything is empty. Everything is in a state of fluidity. The whole world is just a quantum mechanical field. This is Vitarka. The entire science is based on tarka, irrefutable tarka of it, the quantum physics or whatever you call it. That is vitarka, that is samadhi.
