Chakras or whirling energy centers are very important part of the energy body. Just as the visible physical body has vital and minor organs, the energy body has major,minor and mini chakras. Major Chakras are energy centers which in general are about three to four inches in diameter. They control and energize the major and vital organs of the visible physical body. They are just like power stations that supply life energy or prana to different organs. When the power stations malfunction, the corresponding vital organs become sick or deseased because they do not have enough life energy to operate properly!
The chakras have several important functions:
1. They absorb,digest and distribute prana to the different parts of the body.
2. The Chakras control and energize, and are responsible for the proper functioning of the whole physical body and its different parts and organs. The endocrine glands are controlled and energized by some of the major chakras. The endocrine glands can be stimulated or inhibited by controlling or manipulating the major chakras. A lot of ailments are caused partially by the malfunctioning of the chakras.
3. Some chakras are sites or centers of psychic faculties. Activation of certain chakras may result in the development of certain psychic faculties. For example, among the easiest and safest chakras to activate are the hand minor chakras. These are located at the center of
the palms. By activating these chakras, one develops the ability to feel subtle energies and the ability to feel and sense different parts
of the aura.
Many ancient esoteric books reveal only seven chakras or less. Although a few of them hint on the existence of more than seven. The credit goes to Master Choa kok Sui for explicitely revealing and explaining in detail the closely-guarded secret of 11 major chakras in his book, Miracles through Pranic Healing.
