I wouldn't put much fear into pursuing shamanism. From my vantage point, it's a very natural and even human thing to take interest in. Whether it produces any positive effect (or none at all) is solely dependent upon the individual, however.

For a very brief period I was acquainted with an Apache who partook of peyote for spiritual purposes alongside the guidance of a shaman. The synopsis of the event he told me sounded very very surreal.

The fascination in shamanism for me lies in the act of bestowing various living things, even a flower, with respect and reverence. From a certain perspective these things can be seen as magick - and they are; possessed with a spirit all their own. What's not to revere? I have one single flower upon my terrace which I water daily and it never ceases to fill me with awe when, a single day later it has grown tremendously, or gone from being wilted and dry to vibrant and green after the mere passing of one night! Use whatever word you choose, to me, as simple as it may seem, that's magick.

There are gurus, shamans, et all who can give you this kind of insight, sometimes just from having a conversation from them - and then your whole world becomes one awe-inspiring wonder. But I don't think online can replicate this, it's really very crucial to consult with said individuals in the physical realm
