Alchemy would seem to be something like siddhis, but one could argue that you have to grow spiritually in order to acquire them. The important thing is not to think that this is the point, or to become obsessed with them.

I'm very happy for you to write your own thoughts on my work. I can't always guarantee to get into lengthy discussions, however.

I am aware of your post on lists. I tend to create my own one for a long series, but may investigate further.

Regarding astrology, I have written a whole (unpublished) book about it, which I am gradually uploading to Medium chapter by chapter, although I haven't done it for a while – other topics have preoccupied me. The whole of part 1 is there, however, so that could keep you going for a while.
