Srila Gurudeva Bhaktivedanta Narayana Maharaja: One can change or give up that guru under two conditions or circumstances. At the time of selecting a guru and taking diksa, the sisya may not have examined him. He may have become overwhelmed and taken initiation at once, and afterward he may have heard so many things, from books like Srimad-Bhagavatam and from superiors, that this guru cannot actually help him. He may now think, “I took diksa fifteen years ago but there has been no advancement.” He can quickly give up that guru. I know so many gurus who never chant. They say to others, “You should chant,” but they have no time to chant. They are always talking on telephones, with one phone on each ear.

They are absorbed in management, and they attend many meetings that bring no solution to anyone’s problems. If the disciple later on understands this, he should give up that guru, and Srila Bhaktivinoda Thakura has quoted so many slokas in this regard.

The second parastiti (condition) is as follows: Suppose at the time of taking diksa, one’s gurudeva was really following the Vaisnava line, he was a madhyama-adhikari, and he knew many tattvas like krsna-tattva, and maya-tattva. Then, after some time, he began to take the association of a mayavadi, sahajiya, or materialist. He stopped chanting, and after that he began to criticize Vaisnavas, no longer accepting the guru-parampara. The sisya should at once give him up, as one passes stool. When one gives up stool, he becomes very happy and he feels fresh. Similarly, upon giving up all these ‘kan-gurus’, the aspiring devotee will be extremely happy.
