chakra, (“wheel”), any of a number of psychic-energy centres of the body, prominent in the occult physiological practices of certain forms of Hinduism and Tantric Buddhism. The whirling wheel-like disc called the Sudarshana Chakra is the spike-laden divine weapon of Vishnu, one of the principal Hindu deities. The discus, which is also associated with the mind and the "wheel of time," is seen in the flag of India and commonly in the hand of artistic renderings of Vishnu.
The energy chakras are conceived of as focal points where psychic forces and bodily functions merge with and interact with each other. Among the supposed 88,000 chakras in the human body, six major ones located roughly along the spinal cord and another one located just above the crown of the skull are of principal importance. Each of these seven major chakras (in Buddhism, four) is associated with a specific colour, shape, sense organ, natural element, deity, and mantra (monosyllabic prayer formula). The Third-Eye Chakra, for example, called the ajna chakra, is commonly marked with a bindi, the traditionally red dot worn by Hindu, Jain, Sikh, and Buddhist women and occasionally men on the forehead between the eyebrows. This chakra sees the inner world just as physical eyes see the external world, and the bindi helps its wearer access one’s inner wisdom and interpret matters in an unbiased, rational manner. The most important chakras are the lowest one (mūlādhāra), located at the base of the spine, and the highest (sahasrāra), at the top of the head. The mūlādhāra encircles a mysterious divine potency (kuṇḍalinī) that the individual attempts, by Yogic techniques, to raise from chakra to chakra until it reaches the sahasrāra and the realm of self-illumination.
