Bhagavad Gita 4.30

अपरे नियताहाराः प्राणान्प्राणेषु जुह्वति।सर्वेऽप्येते यज्ञविदो यज्ञक्षपितकल्मषाः॥

apare niyatāhārāḥ prāṇānprāṇeṣu juhvati |sarve'pyete yajñavido yajñakṣapitakalmaṣāḥ ||

Others who regulate their diet offer life-breaths in each life-breath. All these are knowers of sacrifice, whose sins are destroyed through sacrifice.

Others, controlling their diet, sacrifice their worldly life to the spiritual fire. All understand the principle of sacrifice, and by it their sins are washed away.

Our plain-language meaning of this verse is waiting for scholar review.
