Bhagavad Gita 9.4 · Krishna
Everything rests in Me
मया ततमिदं सर्वं जगदव्यक्तमूर्तिना।
मत्स्थानि सर्वभूतानि न चाहं तेष्ववस्थितः॥
mayā tatamidaṃ sarvaṃ jagadavyaktamūrtināmatsthāni sarvabhūtāni na cāhaṃ teṣvavasthitaḥ
All this world is filled by Me in My unseen form. All beings rest in Me, but I do not rest in them.
What it means
Krishna offers a mystery. He fills the whole world in his unseen form. Every being rests in him. Yet he isn't contained in any of them. Like the ocean holding countless fish without being any fish. He holds everything, and nothing holds him.
The story
Arjuna sees armies, horses, chariots. Krishna says every one of them rests within him. The whole battlefield is held in a reality far larger than the war.
In your life
Remember the sky holding every bird, cloud and plane, while staying just the sky. Next time you feel lost in the details of life, remember what holds them all.
Everything is held. Nothing holds Him.
