Chakra literally means wheel or circle in Sanskrit. In a more profound sense it represents the eddies or vortexes of energy situated along the central shaft of the human body, deep within the astral spine, a long, downward trajectory of the subconscious mind. The chakras are nerve plexes or centers of force and consciousness situated in our inner or subtle bodies. They correspond to the spinal plexuses in the physical body...
...(ganglia, glands and nerve plexes) from which nerves branch out to provide energy to the different parts of the body. They are part of our spiritual anatomy. For, just like our physical body has an anatomy and maps to the physical world, likewise, there is an anatomy of our spiritual selves, as well as maps and guideposts on the path of inner awakening.
The point between the eyebrows, for example is where the mind focuses instinctively in ecstasy or concentration. You might even have observed people frown or knit their brows when engrossed in thought. Comprehension of this concept and concentration on that spot results in consciously focusing the mind there.
Psychically, the seven primary chakras can be viewed as colorful, multi-petaled wheels or lotuses, situated along the spinal cord from its base to the brain. They are as follows:
|1||Muladhara||base of the spine||memory, time, space|
|2||Swadisthana||just below the navel||reason|
|4||Anahata||center of the heart||direct cognition|
|6||Ajna||third eye||divine sight|
|7||Sahasrara||crown of head||illumination, Godliness|
The first is the Muladhara chakra located at the base of the spine and also called the coccyx center. From this chakra branch out nerves to the lower parts of the body: the legs and anus.
The second chakra is the Swadisthana, or sacral center. It is situated approximately an inch and a half above the Muladhara chakra. The nerves of this chakra manage the reproductive system.
The third is the Manipura chakra, opposite the navel in the astral spine, or lumbar center. The nerves of this chakra serve to operate the digestive system and all internal organs and glands in the abdominal cavity such as the spleen, liver, kidneys, adrenals.
The fourth is the Anahata chakra, or dorsal center located in the region of the heart, from which nerves flow out to the heart, lungs, and chest, and thence to the arms and hands.
The fifth or Vishuddha chakra, also called the cervical center, is opposite the throat in the spine. From here nerves drift to the throat, neck, and vocal chords.
The sixth or highest spinal center is the Ajna chakra situated in the medulla oblongata, at the base of the brain. It is the center from which the entire body is fed with prana (life force or cosmic energy).
The seventh chakra is by tradition known as the thousand-petaled lotus, or crown chakra. This is the Sahasrara chakra in the cranium, at the apex of the head.
