The wilderness can change a man............
There is a real transformation that can metamorphose within a man who is alone in the wilderness. He can exit the wilderness fragile, very fragile, he is no longer sure where that which is himself ends and that which is not himself starts.
Everything is kind of fuzzy, and has a softness about it, all things appear slightly blurred to the eye, like after one has been crying, and it can be hard to distinguish where one object stops and another object starts.
He feels weak and vulnerable, but centered. In fact he is stronger, but the feeling of weakness, and vulnerability comes from the loss of arrogance.
There is a clarity about the perfection of everything. Sounds are crisper, colors are different, there are so many more (new) colors now.
He feels as if he is looking through things and through people, this is a very uncomfortable experience, he tries to focus, but he just looks through everything.
Part of him wants to go back to the way it was, before being alone in the wilderness. But he also enjoys the bliss of how it is now. He wants to weep for no reason, but for the perfection of everything.
He has change, and can not change back to that which he was before, being alone in the wilderness.
I know not of drugs, but being alone in the wilderness, for long periods will change your perception of the universe. The universe is the same, but you have shifted to a place where you can see, with new eyes, a new heart, and a new empathy for all life. You have been born a second time, and are a child of the wilderness.
There was a time long ago, that a man was encouraged to go into the wilderness alone for a extended period, so that he might find wisdom about life. Sad it is discouraged today. Welcome home....welcome home. Home from the wilderness, for he free to return at any time to your true nature.
