I think Zen is about experiencing the truth by experience, which is beyond
words. I don't think there's anything wrong with talking about Zen socially.
I think Zen is about getting back to the root of Buddhism. The four noble
truths of Buddhism are suffering, the accumulation of suffering, the
alleviation of suffering and the path away from suffering. Any religion tends
to have a lot of ideology around it and Zen is about getting past that.
Personally I feel like Zen is about stilling the mind, which it has in common
with Yoga.
