People have dramatic ideas of magic just as some people may have dramatic ideas about Buddhism and tantra, magic is subtle and magic operates in subtle dimensions, like visualization does, and astrology, and the subtler aspects of the 5 elements.
Ritual is just a focusing tool and aligning and amplification of subtle astral and elemental influences, to a large degree magic is applied manipulative astrology. As in tantric parctice ritual is simply the outer aspect u see, the most important part of the practice is internal, imagination, visualization, shamata and one pointedness, strong directed will, confidence is paramount, and the energy raised and used to propel this is emotional, and astral.
Witchcraft is astral and elemental based.
The best time to use magic to affect change is when something undertaken should have manifested but hasn't, when all the physical actions to attain whatever goal have been done, when all has been tried but there is just something in the way, some obstacle, applied magic may provide the subtle influence to affect a positive direction or remove a negative aspect.
Most magicians don't go around winning lotteries and levitating or many of the other dramatic ideas about practitioners.
Astrology and the days and times of astral influence is really the witches clock, substances imbued with the same astral / elemental qualities are used, it's simply aligning many influences of the same specific type, stacking the cards as much as possible, but the real act is internal, ritual is the directing tool, as we all know merely thinking things doesn't necessarily do much, ambiguous vague will simply dissipates, but when the 3 actions of body, speech, and mind are in play and focused and directed one way then this is focusing and directing power. We know ritual from vajrayana of course.
Never underestimate the power of the mind, of imagination, of one pointedness and visualization, the world is not solid, we are all magical creations in a sense. Never underestimate the subtle aspects of the 5 elements for the 5 elements are all anything and everything is made of. And astral influence is subtle but can be used and is known and employed, just as it is in astrology.
But u are right if u want to classify as a witch or magi one who has the actual siddhi, witch power, pervasive prana, tu, whatever u want to call it, this is true, this is a true witch, and this type doesn't need depend on ritual and substances. But this doesn't mean ordinary magic can't be practiced by anybody or be beneficial, all that is needed is understanding of the above said principles and application.
The nonexistence of the transcendence of suffering
is what the protector of the world has taught as the transcendence
Knots tied on space
are untied by space itself.
May I never be seperated from perfect masters in all lives,
and delightfully experiencing the magnificent dharma,
completing all qualities of the stages of the paths
may I quickly attain the state of Vajradhara
