Thought forms that exist in the higher frequency dimensions of the Spiritual Hologram can be directed downward to the frequencies that exist on the conscious and subconscious levels of mind. On either of these levels they can be picked up by people who are sufficiently prepared enough to receive them.
Since each person is already part the hologram, mind reading is merely opening up one’s own psyche to that which is already present. It is the realization of the inherent self-transcendent qualities in us that opens the door. Belief being one of the requirements to access it.
