Hi!

The key practice in Zen is just sitting there focussing on the breath and allowing any shit that arises to 'burn' - the theory is if you sit and endure it burns the self away.

It only takes about 10 years of persistent practice in a monastery to develop one pointedness of mind in the moment, then another decade to let it bed-in apparently.

Personally I just see Satan and all other gods as a distraction from the path, not that I'm not that far along it myself!
