Definition - What does Chidakasha Dharana mean?
Chidakasha dharana is a form of meditation that focuses on the inner space in the mind located behind the ajna (third eye) chakra. It is believed to promote intuition and even allow psychic powers to manifest.
To practice chidakasha dharana, take a comfortable seated position and close the eyes. Place the focus on the inner space behind the forehead with no thoughts, simply observing. Be aware of the body and any visions that appear without judging or analyzing. Finally, as all visions disappear, experience the dark, infinite space.
Yogapedia explains Chidakasha Dharana
Sometimes called “inner visualization,” chidakasha dharana is a Sanskrit term. Chidakasha refers to this inner space or “space of consciousness,” from chit, meaning “consciousness,” and akasha, meaning “space.” Dharana is a Sanskrit word meaning “concentration.” It is the sixth limb of Patanjali's eight-fold path of yoga as described in the Yoga Sutras.
Chidakasha dharana may allow you to see visions of colors and forms, which could be old impressions (samskaras) released by the subconscious mind. Chidakasha dharana is believed to deepen awareness, relax the mind and balance emotions.
