Hi Glow, I see what you are saying regarding the risk of meditation being a shallow exercise when ill-informed or practiced out of context but I would not go as far as to state that practice without "stringent ethical and psychological hygiene" (however one defines that) will shrivel. Unfortunately, there are teachings out there which state that unless a disciple already leads a perfectly pure, virtuous and compassionate life, he/she can never get anywhere within Buddhism. I reject such teachings, as I believe everyone has to work with where they are and what they have. Otherwise a person may find themselves in a catch-22 situation; believing they are not virtuous enough to practice and, of course, with no practice comes no spiritual development. Daily anapanasati can yield great fruit. If done correctly it brings transformative insight into the path, not just stress relief.
