I don't think MH is greedy, but rather honest. He has to support his family just like the rest of us. It's best not to deep into someone's personal life. He offers advice on this forum to all that believe. You can choose to listen or not, but I think it's best to leave his private/family affairs alone. Try to look at the big picture and not from a micro level.
I used to really admire this spiritual healer a long time ago. I would spend hours listening to his speeches, reading/following him, and was really interested in meeting him personally. I finally decided to goto his place of worship/ashram and boy was I amazed! He was completely the opposite of what he was preaching, I mean completely! He would smoke/drink and was having extra marital affairs with women. That was just a few things I saw, but my point is that I was really hurt by his behavior and started to realize that we are all subject to wordly vices, greed, anger, lust, and so on. After that experience it really woke me up and I decided to never again dig too deep into others personal lives.
Stay Happy! Be Aware, and God Bless..
