QUOTE : Atavistic resurgence, a primal urge towards union with the Divine by returning to the common source of all, is indicated by the backward symbolism peculiar to all Sabbath ceremonies, as also of many ideas connected with witchcraft, sorcery and magic. Whether it be the symbol of the moon presiding over nocturnal ecstasies; the words of power chanted backwards; the back-to-back dance performed in opposition to the sun's course; the devil's tail - are all instances of reversal and symbolic of Will and Desire turning within and down to subconscious regions, to the remote past, there to surprise the required atavistic energy for purposes of transformation, healing, initiation, construction or destruction.
