Philosophies

The Thakura made an onslaught against those who belonged to the apasampradayas who were polluting Gaudiya Vaisnavism by basically thirteen deviant philosophies - 

1. Aula, 
2. Baula , 
3. Karttabhaja, 
4. Neda, 
5. Daravesa, 
6. Sani, 
7. Sahajiya, 
8. Sakhibheki, 
9. Smarta, 
10. Jatagosani, 
11. Ativadi, 
12. Cudadhari and 
13. Gauranga-Nagari. 

These deviant groups, mostly because of their boldness, had been seen by the public as the Gaudiya Sampradaya, though actually none were following the pure Vaisnava regulative principles strictly, as laid down by the followers of Sri Krsna Caitanya (namely the Goswamis). Being a follower of the Goswamis or not is interdependent on qualifying one to be a Gaudiya Vaisnava. For more details on apa-sampradayas one should read the very nice articles, running as a sequil in the "Back to Godhead" magazine 1991 editions on the same, by His Holiness Suhotra Swami, Iskcon.
