And to this day, [those] who...know the self as I am Brahman [the ONE], 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 the ONE].
                                                                       Brihadaranyaka Upanishad, I.iv.10

"Consciousness shines in various external and internal forms.
There is no existence of objects apart from consciousness.
Therefore the world is simply a form of consciousness."
                                                           Kalikakrama, as quoted in the Shiva Sutras translated by Jaideva Singh
