They are pranic centers within the human framework. In each person, there are myriads of chakras. However, only a few principal ones are utilized in yogic practice. These few are the ones which span the full spectrum of man’s being from the gross to the subtle. These main chakras are:
Mooladhara, Swadhisthana, Manipura, Anahata, Vishuddhi, Ajna, Sahasrara.
Mooladhara: This is the center where one is almost totally concerned with obtaining personal security. That is, one’s main motive in life is directed towards obtaining food, a place to live and so forth.
Swadhisthana: This center is associated with the predominant motive of seeking personal pleasures and sensations through food, drink, etc.
Manipura: This is the center of self-assertion. One attempts to dominate situations and other people. One seeks to manipulate the world according to personal wishes. This is expressed in the predominant motive of gaining wealth, respect, etc.
Anahata: This is the center where one begins to love and understand people for what they are, regardless of faults, idiosyncrasies, etc. One begins to accept other people.
Vishuddhi: This is the center where one begins to understand and experience the world as a place of harmony and perfection. It is the center where Shiva consumes the poison and the nectar, meaning that all experiences, good or bad are seen as part of an integrated whole, all of which help to remove one’s personal problems and conditioning and thereby raise the level of consciousness.
Ajna: This is the center where one becomes and aactor on the stage of the world, seeing everything as almost a dream. All actions, thoughts and objects, including one’s own body and mind, are observed from the center of one’s being. This is the witnessing center.
