Personally, I find it interesting to observe the parallels between Zen and the memetic theory of mind put forward by Blackmore, particularly regarding free will. Some find it depressing, I find it mind blowingly enlightening.
I totally recommend reading up on it, but do take it with a pinch of salt. Coming from a spiritual backdrop, even Zen is not safe from the taint of head-up-arse bullshit.
