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.

Krishna describes the sacrifice of breath control, prāṇāyāma.

Even the most physical of disciplines, the control of breathing, becomes a way of offering oneself.
