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.

Others, devoted to control of the breath, offer the outgoing breath into the incoming and the incoming into the outgoing, restraining the flow of both.

Krishna describes the sacrifice of breath control, prāṇāyāma. Practitioners offer prāṇa into apāna and apāna into prāṇa, terms that refer to the two movements of breath, often understood as inhalation and exhalation, though their exact sense differs among traditions. By regulating and finally holding both movements, they still the vital energy. The verse includes the methods of yoga practice within the Gita's broad vision of sacrifice. Even the most physical of disciplines, the control of breathing, becomes a way of offering oneself.
