Meditation has two basic functions — achieving relaxation and improving concentration. Therefore the ideal state for OBE is familiar to meditators and indeed OBEs have occasionally been reported during meditation and yoga. The two main types of meditation are concentration meditation (focusing) and insight meditation (mindfullness). Most kinds of meditation are the concentrative type. One simply focuses his attention upon a single physical object, such as a candle flame; upon a sensation, such as that felt while walking or breathing; upon an emotion, such as reverence or love; upon a mantra spoken aloud or even silently; or upon a visualization as in chakra meditation. Concentration meditation is, simply put, a form of self-hypnosis.
The other main type of meditation, insight meditation, is the analysis of thoughts and feelings in such a way as to cause realization of the subjectivity and illusion of experience. Such meditation is done in an effort to attain transcendental awareness.
Chakra meditation is a special type of concentrative meditation which is basically kundalini yoga — the practice of causing psychic energy (kundalini) to flow up sushumna, energizing the various chakras along the way. A chakra is ‘a sense organ of the ethereal body, visible only to a clairvoyant’ . As each chakra is energized by this practice, it is believed to add occult powers (sidhis), until at last the crown chakra is reached, and with it, full enlightenment is attained.
According to East Indian philosophy, man possesses seven major chakras or psychic centers on his body. In theosophical scheme there are ten chakras, which permit those trained in their use to gain knowledge of the astral world (three of the ten are used in black magic only). Each of the chakras forms a bridge, link, or energy transformer; changing pure (higher) energy into various forms, and connecting different bodies together. The chakras are located along the nadies (a network of psychic nerves or channels) and follow the autonomic nervous system along the spinal cord.
The first chakra, located at the base of the spine at the perineum is the root chakra, muladhara. The second chakra, known as the sacral center, svadhisthana, is located above and behind the genitals. Third of the chakras is the solar plexus, manipura, located at the navel and it is said to correspond with the emotions and also with psychic sight (clairvoyance). The heart chakra, anahata, is the fourth chakra, located over the heart and corresponding with the psychic touch. The fifth chakra is the throat chakra, vishuddha, located at the base of the throat (thyroid) and corresponding with psychic hearing (clairaudience).
The remaining two chakras are believed to relate mostly to elevated states of consciousness. The frontal chakra, (or ‘third eye’) ajna, the sixth chakra, is located between, and slightly above, the eyebrows. Ajna is the center of psychic powers and it is believed to be able to produce many psychic effects. Finally, the crown chakra, sahasrara, located atop the head, (pineal gland) is the seventh chakra. It is referred to as the thousand-petaled lotus and corresponds with astral projection and enlightenment.
To practice this chakra meditation, you simply concentrate on the chakras, beginning with the root chakra, and moving progressively up, as you visualize psychic energy from the root chakra traveling up shushumna and vivifying each higher chakra. As mentioned above the chakras have certain properties associated with them, so that this type of visualization may ‘raise consciousness,’ promote astral projection, and other things — once you have reached ajna and eventually the crown chakra.
