Bhagavad Gita · 9.15

ज्ञानयज्ञेन चाप्यन्ये यजन्तो मामुपासते।एकत्वेन पृथक्त्वेन बहुधा विश्वतोमुखम्॥

jñāna-yajñena chāpy anye yajanto mām upāsate ekatvena pṛthaktvena bahudhā viśhvato-mukham

Others worship Me through the sacrifice of knowledge — seeing Me as one, as separate, and in many forms facing all directions.

— Bhagavad Gita 9.15
