Bhagavad Gita · 9.24

अहं हि सर्वयज्ञानां भोक्ता च प्रभुरेव च।न तु मामभिजानन्ति तत्त्वेनातश्च्यवन्ति ते॥

ahaṁ hi sarva-yajñānāṁ bhoktā cha prabhur eva cha na tu mām abhijānanti tattvenātaśh chyavanti te

For I alone am the enjoyer and the Lord of all sacrifices. But those who do not recognize Me in truth fall from their elevated position.
