I think I read something about ascestics somewhere else on this forum, but this:
The idea is to become more aware of your surroundings, your experiences, your emotions, and to learn to describe them all as if you were observing rather than analyzing them.
Once we’ve achieved greater mindfulness, we can begin to describe the things that upset us emotionally in terms of how they make us feel, with the ultimate goal being to achieve more effective emotional control.
is zen. Apart from the "more effective emotional control", which wouldn't describe the experience of leaving behind the emotions as an expression of attachment.
This isn't a "nature did it first" type post. As a sometimes student of religion I'm fascinated by the way that religions encourage "mindfulness" in practitioners, rather than "wilfulness"
