However it is interpreted, the jagged shape of the
zig-zag carries with it the idea of heat, energy, vitality, and
movement, the archetypal sign for lightning or electricity. The double
zig-zag that makes the astrological glyph for Aquarius could be water or
it could be the life-force itself. The serpent that spirals up the
Caduceus is a soft-ened zig-zag shape. There is an inherent danger in
the zig-zag, and the deities that carry it in their hands do so as a
sign of their own authority and power.
