Bhagavad Geeta Chapter 9 - The Royal Secret
Verse 4 - They are in me, I am not in them.
4. All this world is pervaded by Me in My unmanifested form (aspect); all beings exist in Me, but I do not dwell in them.
5. Nor do beings exist (in reality) in Me; behold My divine yoga! Supporting all beings, but not dwelling in them,is (Me) My Self, the efficient cause of all beings.
