Perhaps where the paths diverge somewhat is in the sticking point of the occultist wanting to get practical about spiritual transformation. However the religions which practice the ritual of Holy Communion are doing nothing less. From the point of view of an outsider, the Communion ritual seems pretty gory.
Practical spirituality is the purpose.
Enlightenment, transformation, and making heaven on earth are the bottom line considerations. The ritual, practice and exploration of the spiritual practice that evokes these concepts for you, is the one that works. With practical advice and wisdom, come closer to realizing your dreams.
