Examiner: How is someone to know who's good and who isn't?Sri Chinmoy: Well, there are a few easy ways to recognise a false Master. If somebody says that he will be able to grant you God-realisation overnight, in the twinkling of an eye, then you have to discard that Master. Nobody can realise God overnight or in a matter of days or weeks. And if somebody says that he will be able to grant you God-realisation if you give him a large sum of money, this is absurd. Like that, a few people claim that they will be able to teach you realisation or spiritual powers for a sum of money. If they make it sound like instant tea or coffee, then it is absurd. Those teachers are undoubtedly not real ones.
