I don't disagree, actually. The world-denying (or rather life-denying) aspect of many Buddhist teachings is what led me to abandon Buddhism. Funny you should mention Stoicism. That's what I looked into after I left Buddhism. But I found the Stoics lacked the Buddhists' compassion. As much as Buddhism focuses on suffering, they also have a deep thread of compassion that I haven't found anywhere else. Those teachings really helped me survive some deep depressions Eventually, I ended up spending time with the Epicureans. It's a shame so little of Epicurus' work survives, because I think he was brilliant and probably would have had a lot to offer us in present post-postmodern times.
I like what I've read of Taoism... or what I can understand of what I read, lol. Those mystical translation don't help.
