The clairvoyant may see forms which are elsewhere, but he cannot see the formless.
The telepathic may communicate directly with the mind of another, but he cannot communicate with one who has achieved no-mind.
The telekinetic may move an object without touching it, but he cannot move the intangible.
Such abilities have meaning only in the realm of duality.
Therefore, they are meaningless.
Within the Great Oneness, though there is no such thing as clairvoyance, telepathy, or telekinesis, all things are seen, all things understood, all things forever in their proper places.
