"And to this day, [those] who...know the self as I am Brahman [IS-ness], become all this universe. Even the gods [any other dimensional beings] cannot prevent his becoming this, for he has become their Self. ...if a man worships another deity thinking: He is one and I am another, he does not know. He [who does not know] is like a sacrificial animal to the gods. As many animals serve a man, so does each man serve the gods. Even if one animal is taken away, it causes anguish to the owner; how much more so when many are taken away! Therefore it is not pleasing to the gods that men should know this [that they are IS-ness]."
Brihadaranyaka Upanishad, I.iv.10
