Translation:
The Supreme Personality of Godhead said: Sitting on a level seat that is not too high or too low, keeping the body straight and erect yet comfortable, placing the two hands on one’s lap and focusing the eyes on the tip of one’s nose, one should purify the pathways of breathing by practicing the mechanical exercises of puraka, kumbhaka and recaka, and then one should reverse the procedure (recaka, kumbhaka, puraka). Having fully controlled the senses, one may thus practice pranayama step by step.
Purport:
According to this procedure, the hands are to be placed palms upward, one on top of the other. Thus, one may practice pranayama through mechanical breath control in order to achieve steadiness of the mind. As stated in the yoga-sastra, antar-laksyo bahir-drstih sthira-cittah susangatah: “The eyes, which generally see externally, must be turned inward, and thus the mind is steadied and fully controlled.”
