In India today, especially, there are so many bogus gurus cheating the public. The commonly asked question is how to recognize a bonafide guru who is spiritually enlightened. Krishna says in the Bhagavad Gita that one should seek the shelter of a self-realized soul in order to find the truth. So just because one claims to be self-realized and wears a saffron robe cannot be considered self-realized. What then is the symptom of by which one can realize a self-realized soul?
The answer is this - If one does not become angry when attacked for no apparent reason, and if one does not become enlivened when glorified or worshiped, then one has passed the test of self-realization and is considered fixed in spiritual intelligence. - SB 11.11.15
There...when one finds such a soul, we should catch hold of his instructions for dear and never let go, rest assured our destiny is secure. As for other so called gurus and self styled spiritual teachers, we reject them.
