In ISKCON and in many of the saṅgas that have developed from ISKCON, there is a widespread idea that Śrīla Bhaktisiddhānta Sarasvatī Prabhupāda did not support rāgānugā-bhakti. This is not an accurate statement. The accurate fact is that Bhaktisiddhānta did not support Rāgānugā in the same way that Śrī Bhaktivinoda and his predecessors did.
Specifically, Bhaktisiddhānta did not support the contemporary implementation of Dhyānacandra Goswāmī’s system of Rāgānugā-sādhan – especially giving ekādaśa-bhāva immediately on dīkṣa via a “siddha-pranālī.”
Ekādaśa-bhāva – a list of eleven characteristics of a person the practitioner is supposed to identify with – is simply a template given from the guru to the disciple as a starting point for the disciple’s meditation on participating in service in Vraja-līlā. This meditation is an essential, indispensable component of Rāgānugā, but the use of ekādaśa-bhāva, while certainly very helpful when judiciously applied, is not the only way to approach the meditation.
Bhaktisiddhānta Sarasvati was not opposed to the system, but to the casual manner in which it was given to those hardly qualified to utilize the system or practice the meditations.
Bhaktisiddhānta’s opinion here has to be clearly understood and expressed, otherwise we will accept the the very widespread misconception that Śrīla Bhaktisiddhānta Sārasvatī was against Rāgānugā – thereby drawing into serious question whether he is actually a representative of Śrī Caitanya or not, for Śrī Caitanya’s express mission (as described by his immediate followers and biographers) was to propagate Rāgānugā Sādhana.
To learn more on this subject, I highly recommend an excellent essay written by my Gurudeva, Śrī Dhanurdhara Swāmī: Śrīla Bhaktisiddānta and Rāgānugā Sādhana.
