You can always improve on something, the technology is different today, but I would leave it well alone. If there was something that was incomplete, that might be interesting... because I do that on my website.
I think there's been a big problem between religion, or organized religion, and spirituality.
I think that what went wrong with religion is the same thing that went wrong with politics. Is that it became too money based and too controlling. It's just a weakness that we human beings have for control - we want one thing and then we want more and then we want more.
