अपाने जुह्वति प्राण प्राणेऽपानं तथाऽपरे।
प्राणापानगती रुद्ध्वा प्राणायामपरायणाः।।4.29।।
4.29 Constantly practising control of the vital forces by stopping the movements of the outgoing and the incoming breaths, some offer as a sacrifice the outgoing breath in the incoming breath; while still others, the incoming breath in the outgoing breath.
4.29 Others offer as sacrifice the outgoing breath in the incoming, and the incoming in the outgoing, restraining the course of the outgoing and the incoming breaths, solely absorbed in the restraint of the breath.
4.29. - 4.30. [Some sages] offer the prana into the apana; like-wise others offer the apana into the prana. Having controlled both the courses of the prana and apana, the same sages, with their desire fulfilled by the above activities, and with their food restricted, offer the pranas into pranas. All these persons know what sacrifices are and have their sins destroyed by sacrifices.
