&nbsp;The word Chakra, which comes from Sanskrit and means &quot;wheel&quot;, is meant to indicate the seven basic energy centers in the human body. Chakras are centers of subtle psychic energy located along the spine. Each of these centers is connected, at the level of subtle energies, to the main ganglia of the nerves which branch off from the vertebral column. In addition, the chakras are related to the levels of consciousness, to the archetypal elements, to the phases inherent in the development of life, to the colors, which are closely linked to the chakras, because they are found outside our body, but inside the aura , or the electromagnetic field that surrounds each person, to sounds, body functions and much, much more. The Eastern doctrine that has spread knowledge of them in the Western world considers the Chakras as openings, gateways to the essence of the human body. The chakras are usually represented inside a lotus flower, with a variable number of open petals. The open petals represent the chakra in its full opening. On each petal is written one of the fifty letters of the Sanskrit alphabet, which are considered sacred letters, therefore, divine expression. Furthermore, each of them expresses a different activity of the human being, a different state, both manifest and still potential. Each chakra resonates on a different frequency which corresponds to the colors of the rainbow.&nbsp;<br />The seven main Chakras also correspond to the seven main glands of our endocrine system. Their main function is to absorb the Universal Energy, metabolize it, break it down and convey it along the energy channels up to the nervous system, feed the auras and release energy outside.&nbsp;<br />&nbsp;
