Actress Shirley MacLaine offers a line of "eco-friendly" jewelry based on sacred geometry. Above: Swirl to God, an homage to the spiral:

Generally, the spiral represents a broadening of consciousness, which is the destination arrived after a long journey.

In terms of astrology, mysticism and myth the spiral translates into meanings of spirituality and rebirth.

In terms of spirituality, the spiral symbol represents the path leading from outer consciousness (materialism, external awareness, ego, outward perception) to the inner soul (enlightenment, unseen essence, nirvana, cosmic awareness).

In terms of rebirth or growth, the spiral symbol represents the consciousness of nature beginning from the core or center and thus expanding outwardly. This is the way of all things, as recognized by most mystics.

This is just one of many spiritual products offered on her site, an epitome of commerce as an extension of the self. As Ms. MacLaine can affirm, there's little more rewarding than living long enough to go from outside to mainstream.
