Eleven reasons for rejecting Guru
1 - Is arrogant and proud.
2 - Does not know what to do or not do, or gives improper guidance.
3- Teachings are inconsistent, against the conclusions of Srimad Bhagavatam and Gaudiya Vaisnava scriptures.
4 - Has deviated from the path laid out in the bhakti-sastras, or preaches bogus ideas or apasiddhanta against the teachings of the six Gosvamis.
5 - Is envious or antagonistic toward other Vaisnavas.
6 - Disciple is not satisfied with Guru. (aparitosena)
7 - Is unqualified due to poor sastric knowledge, and thus incapable of answering a disciple’s questions on sastra which leaves the disciple doubtful and unsatisfied.
8 - Is ignorant about the position of Krishna and has misconceptions about the truth.
9 - Does not accept Krishna’s pastimes, imitates Krishna or calls himself God.
10 - Opposes Vaisnava philosophy and practice.
11 - Was prematurely accepted without careful examination. And as a result, the disciple sees that all his sadhana efforts are not producing the desired result.
