there are a lot of really good answers and suggestions here . . . . .
as for myself . . i am 100% convinced magick is real Real. . . . i reached this conclusion gradually by establishing a relationship with those tiny inklings and whispers that emerge with Deep Listening . . . . i would have a notion . . listen to it . . . follow its instructions, directions, guidance . . . as in, hey, maybe turn here a block early on your drive . . . or . . call this person right now . . . . these are very very quiet voices . . . . and many many many times, i would choose to do what they instructed and have No reason why and Nothing of any note would happen . . . . . other times . . . i would listen, follow along and . . Kablam! . . . there it would be . . . the thing i'd been looking for . right there on the curb just waiting for me . . . . .
for me, it is a way of calibrating myself to the subtle energies . . . with no expectations, but rather, with Faith that it will all happen the way it's supposed to happen . . . it's like learning a language and a new logic system . . . and it can be really confusing and all consuming and you can really drive yourself nuts with it when youre listening for whispers everywhere and following butterflies around or whatever . . . . . so i dont necessarily recommend any of it!!
i was a part of a visionary shamanic drumming circle for a few years . . there were no plant medicines involved, simply rhythm to enter mild altered states . . . . newcomers would ask all the time, how do i know what im experiencing is Spirit talking or just my imagination? . . . . . i would say, first of all, "Just your Imagination"?! You mean Just that superpowerful Visionary Force in your Head that creates stuff outta Nothing?! "Just" that? . . . . . next i would say something like . . it doesnt matter . . . maybe ask yourself if you feel different after the ritual than you did before . . even if it's super subtle . . . and if you feel different . . how do you feel different? . . . . and get used to noticing really subtle shifts . . . . . . that's where My Magick lives . . . . . . . .
