Taking mushrooms as a of way of develeouping your spiritual side is a very real concept. In fact religions have incorporated the magic mushrooms to enable communes with non mundane entities.
It is much better to do these from a spiritual and scientific stand point that merely as a party drug.
I, for instance, have done mushrooms several times, and have had very enlightening experiences. Although I cannot say that I had an open dialogue with The God, that is the first cause and creator, I have felt very harmonious and in tune with nature, including all that encompasses the ecology around me. More so biotics than abiotics, but let me tell you...trees are incredible, and animals seem to have true thought.
And fire...whoa...very much like an organism...be careful around fire, always keep control of it.
There is plenty of information on shamanistic practices on the net, i merely don't have time to paraphrase.
Google it, see what turns up.
