All efforts to attain spiritual awareness fall within the domain and protection of the Universal Consciousness, or Great Spirit, represented by the unifying circle which has no beginning or end. The moon's cycles are followed for the most auspicious influences upon spellcraft. The waxing phase is the time to bring something into creation or for increase. Full moon is the culmination of power for these purposes. The waning phase is for decrease or removing something from existence.
Dark moon is the ultimate in no energy or power, therefore is used for introspection or divination.
