Bhagavad Gita 9.15

ज्ञानयज्ञेन चाप्यन्ये यजन्तो मामुपासते |
एकत्वेन अलगावत्वेन बहुधा विश्वतोमुखम्

Translation

Others, engaging in the yajña of cultivating knowledge, worship Me by many methods. Some see Me as undifferentiated oneness that is non-different from them, while others see Me as separate from them. Still others worship Me in the infinite manifestations of My cosmic form.
