“There are two approaches to magick: the outward — ceremonial, ritualist; and the inward — mystical.
The distinction between magick and mysticism is often blurred, as the two seemingly different approaches often cross and converge at various points. In ceremonies, rituals, etc., magick generally works
through the external level, while in mysticism it is typically directed inward. The difference is in approach.
The distinctions of magick and mysticism have been best summed up by Kenneth Grant: “There are two methods and two goals which — at first sight — appear to be diverse and opposite. One method is magical, involving outwardly directed energy which seeks union with ‘all otherness’, the other method involves a mystical inward-reaching towards the secret centre of being whose nature is Self-love. It may
be supposed that the first method is for tyros, the second for adepts, but properly understood these two apparently opposite paths are seen to be identical, for ‘all otherness’ is the one Self in different guises”.
This is not to imply a dichotomy between magick and mysticism. By the use of the differing words is meant merely the point of view, of approach — ‘internal’ being the mystical (an ‘inwardreaching’) and ‘external’ referring to the ceremonial (“outwardly directed energy which seeks union with ‘all otherness’”). In this instance mysticism deals with unity, while ceremonial works with dualities. Both words used here refer to the “ability to attract without asking” and to “cause Change to occur in conformity with Will”. This subtle variation in approach has given rise to the corresponding designations of extroverted and introverted”
