Bhagavad Gita · Chapter 9: The Royal Knowledge and Royal Secret

Bhagavad Gita 9.24

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

ahaṃ hi sarvayajñānāṃ bhoktā ca prabhureva ca | na tu māmabhijānanti tattvenātaścyavanti te ||

For I am the one who receives all sacrifices, and their lord. But they do not know me as I truly am, and so they fall.

Modern context

Every offering, to whatever god, is received by the one. Those who do not know this still receive their reward, but they 'fall' afterwards, returning to the cycle. The problem is not the worship but the lack of understanding behind it. It is like sending a letter to the right person without knowing who they are. The letter arrives, but no lasting relationship is formed.
