Universal Mind may be thought of as:

1) The interpenetrating sum total of the minds of all sentient beings in all time-spaces;

2) The omniscient Intelligence emanating or manifesting directly from the undifferentiated plenum-Void; and

3) At advanced stages of realization, not different from one's own mind.

Since Universal Mind is omniscient, it follows that all knowledge (and therefore all power) is available to any individual that "contacts", "merges with", or "realizes itself as identical to" Universal Mind. Such contact or merging occurs momentarily during meditation states such as transcendental meditation, zazen, and the trance state of applied magic. Advanced practitioners of meditative techniques are known to have acquired "siddhis", or supernormal abilities in this manner. Some common siddhis are levitation, teleportation, telepathy, telekinesis, clairvoyance, clairaudience, shape-shifting, creation of thought-forms, and psychic healing.

Individual minds can also realize unity with Universal Mind during wakeful states of consciousness that are not hypometabolic. This happens momentarily in the case of certain psychics, mystics, and magicians, and under more controlled and long-term conditions in the case of Bucke's "cosmic consciousness" and in cases of individuals whose "third eye has been opened" (i.e., whose pineal gland has been fully activated) or whose kundalini has been raised (i.e., whose "serpent power" has been awakened and risen through the channels of the spinal column).

And from The Tibetan Book of the Great Liberation:

"If one knows how to apply in a three-fold manner this knowing of the mind, all past knowledge lost to memory becomes perfectly clear, and also knowledge of the future thought of as unborn and unconceived."
