When I began my doctoral work at Harvard, I quickly learned that ISKCON was a laughing stock in my department. Devotees would come to Harvard Square to jump and run around, banging on drums. We all know the story.
I feel it’s an unfortunate aspect of ISKCON culture that it marginalizes raganuga-sadhana (particularly in madhurya-bhava) to the point it appears non-existent and even undesirable.
Regarding the statement that Raganuga-bhakti is marginalized, that may be a good thing because it should be, literally, at the margins, and not in the center of a large, sprawling, and largely neophyte spiritual society. A margin is “an edge or border” not in itself pejorative, though the verb “marginalize” may have negative connotations.
