Whos to say their is a cycle of rebirth? As a Catholic as I see it the immortal soul lives on forever in either A)heaven or B)Hell after the physical body dies, so from this point of view you are immortal, in that the true essence of who and what you are never dies.
Well for starters Immortality is not physical possible as the body was not designed for it and two Crowley had all sorts of issues a drug problem was one of them. You do not need "drugs" to get his point of view or an etheric view on things. In reality all the drugs do on messages is get messed up so why bother with them? But anyways back to topic immortality is only done with the soul and if you take that the higher consciousness is a concept it moves on while human aspect of the soul does not. Either way you go you can only live forever is through the soul.
Actually, the reason we can't really live forever is because each cell of our body can only reproduce (mitosis) about 50 times, at this point the "caps" that keep out DNA from unraveling (which grow shorter with every Miotic cycle) simply run out, our DNA unravels, and the cell can no longer reproduce and eventually can't even perform its most basic life functions, and dies. So the way as I see it to become immortal, or at least live much longer than we already do, would be to find a way to constantly replenish these DNA "caps". And there actually is a chemical thats been found in certain bacteria in the amazon that can do exactly that.
My personal belief on immortality is that it is unattainable. What begins must end. Even if you could make your body able to constantly replenish it's cells so that in theory you could exist indefinitely, eventually you or someone else would cause you mortal damage and you would die anyway. Somehow, immortality seems like a way of ensuring that when you die, it won't be of old age and likely be of sickness and possibly be painful. But it would be possible to stop old age from taking effect by rewriting the dna sequences which, if it hasn't been done already, is most likely being worked on by talented scientists.
