Quantum spirituality?

I have been doing some reading on Quantum physics and 'Multiple world' theory which causes immense problems when you come to the idea of a soul and religious belief if we don't perceive us as in the 'I' as an individual but a multiple aspect of 'Chris' of which there are many versions and I am purely the 'Chris' circa 2007.

Anyway good bedtime reading but makes my head hurt wrestling with the philosophical and scientific in one argument but for a good explanation of the quantum physics of Multiple world theory here: http://plato.stanford.edu/entries/qm-manyworlds/
