If You Do Not Give Him Up

Tridandiswami Sri Srimad Bhaktivedanta Narayana Maharaja extols the glories of Srila Lokanath Dasa Gosvami - part 2
"Guru-mukha-padma-vakya, citte te koriya aikya, ara na koriho mane asa [embrace within your heart the words emanating from Sri Gurudeva's lotus mouth, desiring nothing else]." If guru is really qualified – if his words and character are not different from the teachings of Krsna, Srimad-Bhagavatam, and all the Vedic literature, if he is quite detached from worldly sense gratification and has some realization – then he is really guru. If you know that all of your gurudeva's words and character is supported by the Vedas, Upanisads, Bhagavatam, and Krsna's words, then don't maintain any hope for anything other than following him. All Vedas, Upanisads, and all the words of Krsna reside in him. We can have strong faith in guru and by serving that guru, krsna-prema will surely come. By following the process that gurudeva is giving, his mercy and prema-bhakti will come.
On the other hand, if you think that the words and character of your gurudeva are different from the teachings of Vedas, Upanisads, Srimad-Bhagavatam, and Caitanya-caritamrta; that he is so much attached to ladies, to his pockets, to name, fame, and position; that he is not absorbed in chanting and remembering very much but still he has thousands upon thousands of disciples, then you cannot have any strong belief in him. You should reject him at once.
There is no need to think, "He is my guru. If I give him up, that will be a big offense." Rather, if you do not give him up, that will be a big offense. Give him up at once. Srimad-Bhagavatam and Krsna (sastra) tell us, "Give up this person, otherwise you are committing an offense." Don't believe his cheating words, saying "If you give me up, that is an offense."
