Anyway, that aside, I collect loads of second hand metaphysical books. Some I read almost straight away, some go on the shelf for ages. Now whats interesting is that in the case of Alchemy and others too, when I get them, I think that they are irrelevant, I might even read a bit, and it means nothing to me, and then goes on the shelf for years. Then I get it out again, years later and start reading it afresh, and it all suddenly falls into place. It suddenly is desparatly relevant. I have found this happen loads of times. Thats why I never throw any of said books away. Its why I have a stack of books on the Kabbalah, that at present are beyond my understanding, but I know one day, they will fall into place as I learn and experience more. (My Kabbalistic knowledge is, at present, basic!)
And that, I think is the same process behind things like the Atlantean time capsule theory. The capsules may well have already been found, but the people examining them, have to reach a certain level of understanding and conciousness, before they realise exactly what they have in front of them. Until then, it seems meaningless and irrelevant, like these books to me, until I reach a level of understanding where I suddenly realise the relevance of what they are teaching.
