Psychedelics are a way of reaching other planes on some occasions, yes. They are actually far from controversial- they've been use by shamans the world over since pre-historic times. They are in fact the inspiration for much of our cave art. However, I prefer not to resort to using them. The same communication with the spiritual can be initiated with obe's and lucid dreaming- essentially all altered states of conciousness.


By the by, I highly reccomend that everyone here read "Supernatural" by Graham Hancock, which deals heavily with this theme and the nature of reality and more. One of the most shocking books I have ever read because he essentially discovered the origin of all spirituality in humankind (and trust me, its where you wouldn't think to find it, at first). Amazing book. Amazing.
