Bhagavad-gītā As It Is · Text 17.13
Food and sacrifice in the modes
विधिहीनमसृष्टान्नं मन्त्रहीनमदक्षिणम् ।
श्रद्धाविरहितं यज्ञं तामसं परिचक्षते ॥ १३ ॥
vidhi-hīnam asṛṣṭānnaṁ
mantra-hīnam adakṣiṇam
śraddhā-virahitaṁ yajñaṁ
tāmasaṁ paricakṣate
Any sacrifice performed without regard for the directions of scripture, without distribution of prasādam [spiritual food], without chanting of Vedic hymns and remunerations to the priests, and without faith is considered to be in the mode of ignorance.
