अहं हि सर्वयज्ञानां भोक्ता च प्रभुरेव च ।न तु मामभिजानन्ति तत्त्वेनातश्च्यवन्ति ते ॥
ahaṃ hi sarvayajñānāṃ bhoktā ca prabhureva ca |na tu māmabhijānanti tattvenātaścyavanti te ||
I am indeed the enjoyer and the lord of all sacrifices. But they do not recognize me in my true nature, and so they fall back.
Explanation
Krishna is speaking to Arjuna. Having said that worshippers of other deities are in fact worshipping him, though not by the proper method, he now says that he is the one who receives and presides over every sacrifice (yajña). Those who do not know this truth (tattva) fall away, which commentators read variously as slipping back into rebirth or missing the highest goal.
