Joshomatinandan: I asked Prabhupada about a revered and famous sadhu, Dangari Maharaj, who was then the biggest Bhagavat reciter in India. He would shed tears when he recited the Bhagavat, and the people in the audience would cry too. Prabhupada said, "I don't know about him. What does he say?" I said, "He speaks about Krishna's pastimes, but he also says that you can worship whomever you believe in. You can chant om nama shivaya or hum durgaya namah. There are several mantras that he prescribes, even though in his own katha he generally chants Hare Rama Hare Rama, Rama Rama Hare Hare, Hare Krishna Hare Krishna, Krishna Krishna Hare Hare."
Prabhupada said, "If he thinks that the name of Krishna and the name of the demigods are the same, then he is not Dangari, he is dhangari." Dhanga means pretension. He said, "The Vaishnav will not say that the holy name of Krishna is equivalent to anything else." Prabhupada never judged a person by his looks, his name, his title, or by the tears he shed, but he judged a person by what he said, by his philosophy and siddhanta.
