NICE, LACONIC FABLE IN SHUDDHA-ADWAITA (PUSHTI-MARG) STYLE:
"Rama, a school-going boy, said to his class-fellow Krishna:
“Look here, Krishna, if you can tell me where God is, I shall give you 1 rupee.”
Krishna replied, “Brother Rama, I shall give you 10 rupees, if you can tell me where God is not.”
Expanation by Swami Shivananda Saraswati: "God is an absentee landlord of this world. He is hiding Himself within these objects. He is the Indweller within these objects and the Inter-Penetrating Presence or Essence or Substance.
You will find in "Shree Shvetashwara-Upanishad":
“One Shining Being sits hidden in every creature, pervading all, the Inner Self of all beings, the watcher of all acts, abiding in all created things, the witness, the pure Consciousness, the Absolute, free of all attributes."
