I'm worried about a friend

He has taken up a spirituality phase that seems to be doing him more harm than good!

Before he got serious about this stuff he was calm, easy going,relaxed, and enjoyed many different things. Now he looks 20 years older seems more stressed out about the simplest things and is not very scociable at all, When out he is more arguementitive and tends to seem to get pissed off and leave early.

If spirituality is about bettering yourself why should it seem to be bad for him?

My major concern is that the guru guy he seems to be following might be after financial gain to fund part of a Toronto chapter of his cult or whatever this thing is.

My buddy seems to be cutting himself off from the friends that really care about him!

He goes through bouts of depression and won't realize that he may be being sucked in to some false reality while being isolated from the real world!

Any advice would be apriciated!
