"Benefits to the students that practice Nada--as soon as their mind forms the habits of listening to the inner sound of the Nada, it will never be disturbed by external sounds. By daily practice of Nada, the mind becomes firm and attracted by Nada,--it surely becomes one with Nada. As the sharp goad is best to control the mad elephant, so the Nada is best to control the mind. The Nada holds the mind fixed, as a bird cannot fly without wings. Those Yogis who have mastered the Nada practice are never disturbed by any other sound; they are liberated and emancipated."--H. Y. .

Yogi in Samadhi does not feel pain, thirst, hunger, heat or cold, nothing can harm him, his body does not decay, death never comes, near him. He is equal to God.

The Following is taken from The Yoga Aphorisms.--Chapter III--IV.
