There are some who practice controlling the vital energy and governing the subtle forces of prana and apana, thereby sacrificing their prana to apana, or their apana to prana.
Translated by Shri Purohit Swami
Others offer as sacrifice the outgoing breath into the incoming, and the incoming into the outgoing, restraining the flow of the outgoing and the incoming breaths, solely absorbed in the restraint of the breath.
Translated by Swami Sivananda
