What you think is impossible starts happening.

Give a chance for miracles to happen. It can happen when you are hollow and empty. When both, your heart and mind are pure and clear, then positive energy rises in you. 

But if your mind is full of negativity, and if you are stressed out; or if you are complaining about this and that, and grumbling and griping, then no miracle is possible. Even regular work which has to happen does not happen. Simple things do not happen because energy is low and negative. When energy is high, what you think is impossible starts happening. 

- Sri Sri Ravi Shankar
