Hoodoo root works is derive from the voodoo/vodun. Talismans, conjuring, spells, and more to the point prayers used in hoodoo baseline from religion. The work requires use, recognition, attachment and/or contact of deities, spirits and/or God.
It would be pointless to copy or use the form and disregard or even more to the point deny there is an entity or existence. Is the practice not a system you implement on faith, a pursuit or interest to a power which someone ascribes supreme importance?
