Dandavats! All Glories to Sri Guru and Sri Gauranga!
Spiritual degrees – Bhakti Sastri, Bhakti Vaibhava, and Bhaktivedanta (when available) – shall be a strongly recommended qualification for being granted no objection status to serve as a guru in ISKCON.
How can I find out more about the spiritual degrees? Where are they taught?
Hare Krishna Suresh Prabhu, the MI (Mayapur Institute) and the VIHE (Vrindavan Institute of Higher Education) both offer courses whereby you can get Bhakti-sastri and Bhakti-vaibhava degrees. As far as I understand Atul Krishna Prabhu in Mayapur is now working on the curriculum for a Bhakti-vedanta degree and there are plans in the future for making a course offering Bhakti-sarvabhauma. Another ISKCON project offering similar courses and degrees, is the Bhaktivedanta College in Radhadesh Belgium.
