The Gheranda Samhita

Purification, strength, steadiness, calmness, lightness, realization, and abstraction are the seven means of perfecting the body.

the body the self is consciousness. It is without a second, eternal and supreme. Because it is separate from the body, realize that you are free from passion and vices.

All the creatures of the earth, all the creatures of the air, plants such as trees, shrubs, creepers, vines, grasses, water, and mountains: know all these to be Brahman and see them all in the self.

After becoming disinterested in one’s body, one’s children, one’s wife, one’s relatives, one’s friends, riches, and everything else, one can attain samadhi.

I am Brahman and nothing else. I am Brahman alone and do not suffer. My form is truth, consciousness, and bliss. I am eternally free. I abide in my own nature.

From pranayama, lightness arises and from dhyana, realization of the self. Through samadhi arises abstraction and liberation itself; in this there is no doubt.

The six cleansing techniques bring about purification and asanas bring about strength; mudras bring about steadiness and pratyahara brings about calmness.

Purification, strength, steadiness, calmness, lightness, realization, and abstraction are the seven means of perfecting the body.

Just as from studying the alphabet one may understand the scriptural teachings, so by practicing Yoga one may obtain knowledge of the Ultimate Reality.

There is no fetter like illusion, no force greater than Yoga, no friend greater than knowledge, and no enemy greater than ego.
