The “psychic eyes”.
Focus on each individual chakra, one at a time. Visualize them as little white stars, like miniature suns. As you inhale, absorb white energy into the chakra. As you exhale, vibrate “AGIOS” or “ANSUZ” while visualizing the chakra growing. Repeat 9 times per chakra.
Repeat at least once a day for 60 days in order to develop rudimentary psychic faculties–for instance, as in clairvoyance, seeing auras and shamanic visioning; as in clairaudience, reading thoughts and hearing “astral music”.
