one of the lost gospels???
It's taken from the film 'Stigmata' (excellent film) which itself took it, in part, from the Gospel of St Thomas. Verse 77 says "Cleave a piece of wood: I am there. Raise up the stone, and ye shall find me there". The rest is, I think, made up for the film. However, it does represent perfectly my views on what God and religion are all about!
As for spirualism, that's a different thing entirely!
