Purity is when there is no anxiety, no worry, no thinking.

The whole thrust of yogic philosophical and scientific inquiry has therefore been to examine the nature of being, with a view to learning to respond to the stresses of life without so many tremors and troubles.

When you cannot hold the body still, you cannot hold the brain still. If you do not know the silence of the body, you cannot understand the silence of the mind. Action and silence have to go together. If there is action, there must also be silence. If there is silence, there can be conscious action and not just motion.

The yogi learns to forget the past and takes no thought for the morrow. He lives in the eternal present.

Awareness must be like the rays of the sun: extending everywhere, illuminating all.

Pranayama teaches the aspirant to regulate his breathing and thereby control the mind.

Death is unimportant to a yogi; he does not mind when he is going to die. What happens after death is immaterial to him. He is only concerned with life-with how he can use his life for the betterment of humanity. Having undergone various types of pain in his life and having acquired a certain mastery over pain, he develops compassion to help society and maintains himself in purity and holiness. The yogi has no interest beyond that.
