Does instantaneous magic exist like in Harry Potter and what not? Would that kind of magic be too much to be able to materialize in this 3D realm? If you can do anything in the astrals in astral projection, why can't we manifest things like that here? I've just recently watched all of Harry Potter (never did before) and it just made me more curious about that type of magic.
In my opinion, no we cannot grasp that type of magic. That being said, astral projection has no scientific proof of people actually spiritually leaving the body. I myself am trying astral projection and in my opinion I think I will get there one day, but my answer is no.
You will get there? You NEVER will. Not with that negative attitude. On a different note, remember that you have to be very patient in this art. You have to form alliance with your astral self. Your etheric body is nearly not unlike a separate being coexisting with you subconscious. That being said, i invalidating its existence will get you nowhere practically, and also, theoretically. If you don't respect your astral being, they will never coexist with you consciously. Unless, that's what you really want...
