The False Guru Test
though some on the list do not resonate precisely as they are worded, this one point is to be considered:
Is not interested in you personally: If a teacher or guru does not have time to interact with you personally, then you may as well read his teaching from a book, because merely being in his/her presence [or doing myriad postures they direct, week after week, year after year] doesn't help you find realization inside you. You may model some of his spiritual characteristics, but that often only places you deeper in illusion.
