13. As the outer part of a pot planted in the earth appears to sight, so the apána breath stretching to the distance of twelve inches just opposite to the tip of the nose in the air on the out side, is perceptible to the yogi, and is called Kumbhaka by the learned. 14. The exhaling air which rises from the heart, and extends to the tip of the nose, is styled the primary and external _puraka_ breath ([Sanskrit: ádyah váhyapúrakam]) by the adepts in Yoga practice. 15. There is another (or secondary) external _puraka_ air known to the wise, which takes its rise from the tip of the nose, and extends to the distance of twelve inches out-side of it. 16. After the prána breath sets out-side the nostrils, and before the apána breath has yet its rise, this interval of the entire abeyance of both, is known as the state of perfect equalization, and termed the external Kumbhaka. 17. The air which breathes out in the heart or pulsates within it, and without the rising of the _apána_ breath; is styled the external _rechaka_ in the Yoga system; and its reflection confers perfect liberation to man. 18. And this rising at the distance of twelve inches, in another kind of it and called the strong _rechaka_. 19. There is another kind of _puraka_, which is on the outside of the _apána_; and when it stretches to the inside of the navel within, it is known under the names of Kumbhaka &c. 20. The intelligent man who meditates by day and night on the octuple nature, and course of the _prána_ and _apána_ or the inhaling and exhaling airs, is not doomed to be reborn any more in this miserable earth. 21. I have thus related to you the various courses of the bodily airs, a restraint of which in the waking and sleeping states of man, as also in his states of sitting and waking, is productive of his liberation. 22. Though these are very fleeting in their natures, yet they are restrained by the good understanding of man, even when he is employed in his work or is in his act of eating. 23. The man that practises the _Kumbhaka_ or suppression of his breathing within himself, cannot be employed in any action; but must remain calmly in this act of suppression, by giving all external thoughts and actions. (_i.e._, as in a state of torpidity). 24. A few days practice of this Yoga, by abnegation of all outward objects from the mind, enables a man to attain to the state of his solity, or his unity with the sole entity of the Deity. 25. Intelligent men have no fondness for worldly things, but bear an aversion to them as a holy Brahmán has against the sweet milk contained in a flask of skin. They remain regardless of visible objects, with his eyes closed against them, as a blind man takes no heed of out-ward appearances.
