That's a valid reason. So is "I wanna knock some of the BS in my head loose".

I may be close minded, but "To receive the essence of Grandmother's wisdom and understand the psychic vibrations, not within us, but beside us, as I'm guided by the Jaguar riding the Anaconda, who is really the glory beyond our lesser selves, being to us a more perfect realm as Grandmother wishes it through the greater understanding of our abundant vision..." doesn't really sound like a reason.

Not that I'd stop someone from doing it for that reason, but I fail to see how it's the least bit useful and it seems ripe for exploitation.
