I'm reading James Swartz's book "The essence of enlightenment: The science of consciousness" which is an introduction to traditional Advaita Vedanta. The chapter "A qualified teacher" is very pertinent to Mooji. Here's two quotes from the chapter:
Quote
Enlightenment has no meaning apart from how you live. It is quite amazing in this day and age that the “crazy wisdom” idea still has legs. “Do as I say, not as I do,” is not a teaching. What use is enlightenment if it amounts to nothing more than a license for the ego to indulge its cravings? It is quite sad that so many teachers have compromised themselves over the years and given truth a bad name over the most banal vices: money, sex, fame, or power. One imagines that the vices of the enlightened should somehow be more exotic.
Quote
A teacher who convinces you that your ego needs busting or that your mind needs to be destroyed is very dangerous. Fame does not a teacher make; groups of people can be as deluded as individuals. You will notice that the teachers around whom cults of personality develop invariably make the mind the enemy. Whenever a doubt happens, you are told that it is just “mind” and asked to dismiss it. If you find yourself with this kind of teacher and teaching, it means that he does not have a valid means of knowledge and is power hungry or needy. It is amazing how many popular teachers actually need your love. If you feel that a teacher needs you for any reason, head for the hills. You are asking for trouble. A true teacher is dispassionate and self-fulfilled and has nothing to gain by teaching you.
