And you dont learn alchemy you live it. if you are turely intrested in it go for it but its not one of those things were you learn all of its secrets in a matter of months or forget about because you got bored.
The site I had put up is a site of free pdf's on more than just Alchemy.
Also, Alchemy does take time as it is about the actual process and doing more than it is just about reading. Also know that it is a spirituality as well and that it spans all across Europe and some into Asia and Egypt, so you will get things like Arabic and other texts. Just remember the context and that you can apply it without deity or even with many as well, as I have.
