Bhagavad Gita Chapter 4 Verse 30 भगवद् गीता अध्याय 4 श्लोक 30 अपरे नियताहाराः प्राणान्प्राणेषु जुह्वति। सर्वेऽप्येते यज्ञविदो यज्ञक्षपितकल्मषाः।।4.30।। English Translation - Swami Sivananda 4.30 Others who regulate their diet offer life-breaths in life-breaths. All these are knowers of sacrifice, whose sins are destroyed by sacrifice. English Commentary - Swami Sivananda 4.30 अपरे other persons? नियताहाराः of regulated food? प्राणान् lifreaths? प्राणेषु in the lifreaths? जुह्वति sacrifice? सर्वे all? अपि also? एते these? यज्ञविदः knowers of sacrifice? यज्ञक्षपितकल्मषाः whose sins are destroyed by sacrifice.Commentary Niyataharah means persons of regulated or limited food. They take moderate food. By rigid dieting they control the passions and appetites by weakening the functions of the organs of action.Yogis pour the lifreaths as sacrifice in the controlled lifreath. The former becomes merged in the latter.Performance of the above sacrifice leads to the purification of the mind and destruction of sins.
