You do not any drugs to reach enlightenment or to break your limitations or to see in higher realms. You do not need them, but they a large help. Meditation takes a lifetime of practice to get where the psychedelics take you in just a few short hours. I guess its sort of a short cut, or a glimpse into the other side. Psychedelics are great for people who have no concept of life beyond this mundane world. If you were born in a family who taught mediation and enlightenment and you were on that path to begin with then psychedelics could just be a set back, and confuse your practice. But for most people in the world whose lives revolve around tv dinners and shopping malls, psychedelics are great way to burst open the doors, show your their is more to life then meets the eye. For me I had no clue of enlightenment until something pryed open the door and showed me something of what that term even means. Because many people who use that term have no idea what they are even describing. The masters don't want to tell you, but even they know the place of these things. They are not a accident in nature. They were put here specifically for your enlightenment. They are not a separate vehicle to truth. They are part of truth, something you must pass through, part of the process. They have their place and connection to nature and to the truth. Don't be fooled, you do not work on a real consciousness when you mediatate and a false consciousness when you trip out. Consciousness is consciousness and even though the modes to which you unleash consciousness are different, the effects are similar. Shit is real!
Maybe it's just all in our heads. What you appear to be describing is a contention between the ego and the Self. Yes, substances can destroy the ego (temporarily), but I have found them to be limited teachers. Instead, I look inward. ". . . to know yourself is enlightenment."
My response: energy can be neither created nor destroyed. When I die, I'll simply change form. =) Is there more to the world than meets the eye? Possibly. However, seeing as how I am unable to sense it, it is difficult for Me to be certain either way. Although it may be intriguing to speculate on such matters, I have found that it is a much more efficient use of my time and energy to simply work on Myself as a human being. In the way of perception, I am limited by both My senses and My knowledge, and I know Myself well enough to know that I can create any experience for Myself if I simply believe in something profoundly. The human mind is extraordinarily powerful, which can be both a good, and bad, thing. Death is a distraction--as is providence. Much of humanity is weak. Many humans believe that they require external guidance because they lack both the will, and the confidence, to construct a harmonious constitution of their own making. I, personally, view religion as a tool--or perhaps it would be better to describe it as a school of thought. I, for one, believe that the interconnectedness of the universe is readily apparent, and that means putting things into perspective and looking at the bigger picture. "Highly evolved people have their own conscience as pure law." Substances, also, can be viewed as tools. Have my past encounters with drugs introduced Me to new ideas? Yes, but I firmly believe that I could've stumbled upon those ideas without being under the influence of any substances. I wouldn't go so far as to call it a shortcut, but some drugs certainly do stimulate our imagination. What's most important is to remain grounded in reality so that we do not end up living in a fantasy world of our own creation.
I am an Atheist, and was the kind of Atheist who said all there is is evidence and the physical world. It wasn't really psychedelic drugs that changed my opinion of this, but they did push me. I'm still an Atheist but I think there's something waiting for all of us. They say when you die you release all the DMT stored in your Pineal gland, and if that much DMT is released in one instantaneous moment you could in theory lose perception of time and trip forever. I'd be fine with that too.
