Bengali Vaishnava reformers in the 19th century reclaimed Vaishnavism as a noble indigenous tradition and rehabilitated its reputation, setting it apart from low-caste, antinomian, suspiciously Tantric, heterodox Vaishnava movements. For this purpose they employed the notion of apasampradāya – a term widely used by Bhaktisiddhanta Saraswati, by Bhaktivedanta Swami Prabhupada, and by his followers. The term (apa- , prefix for inferior, bad, defecting, deviating, + sampradāya, a religious tradition, community, often translated as sect) is glossed as a deviant religious sect and used by orthodox Vaishnava spokespersons to refer to those communities that they envisage as degenerate, immoral, or unauthorized.
In the prolific writings of Bhaktivinoda Ṭhākura, is there any explicit mention of the term 'apasampradaya'? Can anybody provide a reference?
