Discipline of Meditation and Mental Restraint
अपरे नियताहारा: प्राणान्प्राणेषु जुद्बति | सर्वेड्प्येते यज्ञविदो यज्ञक्षपितकल्मषा:
apare niyatāhārāḥ prāṇān prāṇeṣu juhvati | sarve 'py ete yajñavido yajñakṣapitakalmaṣāḥ ||
另有人节制饮食，将自身的诸般生命之息奉入生命之息之中——以调御诸气而行内在之祭。凡此诸人，皆为知祭者，其垢染由祭行之纪律而渐被销尽。

Educational Q&A
True yajña is not limited to external ritual; disciplined self-regulation—especially of food and the vital energies—can itself be an inner sacrifice that purifies the practitioner.
Arjuna describes different kinds of sacrificial practitioners. Here he points to ascetics who regulate diet and perform an inward offering of the life-breaths into the life-breaths, and he concludes that such people are genuine knowers of yajña whose faults are reduced through their practice.
