I hope you all realize that the idea of the chakras is only a relatively recent addition to Western Ceremonial Magick and their use is neither necessary nor mandatory. They have only become part of Western occultism because of the heavy influence of Theospohy, whose founder, Helena Blavatsky, was a bit too enamored of Eastern mysticism (she was also the one who made up the mythology of Atlantis being populated by sorcerers who were punished for overstepping their bounds that a lot of magicians and New Agers seem to believe) and the Golden Dawn, who took the lore of Theosophy and ran with it, adding in their version of Jewish mysticism.
Every culture on Earth, has its own ideas about the human energy system. The Hindu chakras and the Taoist dan tien and meridians are only the two most well known due, in part, to accessible information about them.
