विधिहीनमसृष्टान्नं मन्त्रहीनमदक्षिणम् । श्रद्धाविरहितं यज्ञं तामसं परिचक्षते ॥ १३ ॥
vidhi-hīnam asṛiṣhṭānnaṁ mantra-hīnam adakṣhiṇam śhraddhā-virahitaṁ yajñaṁ tāmasaṁ parichakṣhate
Translation
Sacrifice without proper method, with no food distributed, no mantras, no offering to the priests and no faith, they call tamasic.
Hindi Meaning (हिंदी अर्थ)
जो यज्ञ शास्त्र-विधि से रहित, अन्न-दान से रहित, मंत्रों से रहित, दक्षिणा से रहित और श्रद्धा से रहित हो, उसे तामस कहते हैं।
Commentary
Tamasic worship is careless and empty: no method, no sharing of food (asrishtannam), no sacred words, no gratitude to those who serve (dakshina), and above all, no faith. Notice that sharing food is named as an essential part of worship. Prasad and bhandara are not extras.
