Anodea Judith (1996: p.5) provides a modern interpretation of the chakras:
A chakra is believed to be a center of activity that receives, assimilates, and expresses life force energy. The word chakra literally translates as wheel or disk and refers to a spinning sphere of bioenergetic activity emanating from the major nerve ganglia branching forward from the spinal column. Generally, six of these wheels are described, stacked in a column of energy that spans from the base of the spine to the middle of the forehead. And the seventh which is beyond the physical region. It is the six major chakras that correlate with basic states of consciousness…
