Sloka 17.13
विधिहीनमसृष्टान्नं मन्त्रहीनमदक्षिणम् ।
श्रद्धाविरहितं यज्ञं तामसं परिचक्षते ॥
విధిహీనమసృష్టాన్నం మన్త్రహీనమదక్షిణమ్ ।
శ్రద్ధావిరహితం యజ్ఞం తామసం పరిచక్షతే ॥
vidhihīnamasṛṣṭānnaṃ mantrahīnamadakṣiṇam |
śraddhāvirahitaṃ yajñaṃ tāmasaṃ paricakṣate ||
About chapter 17
Arjuna asks about those who worship with faith but without following scripture. Krishna explains that faith takes the colour of one’s nature — sattvic, rajasic or tamasic — and shows how the same three qualities appear in food, sacrifice, austerity and charity. He closes with the meaning of “Om Tat Sat”, which sanctifies every act of worship.
