Aurobindonian

[15] This adjectival form of Sri Aurobindo was coined by senior disciple and author Amal Kiran (K. D. Sethna) and has since become standard, if a google book and google scholar search are anything to go by. However Tusar N. Mohapatra has recently argued that "The last o in Sri Aurobindo is not necessary for pronunciation of the name, and hence a simple Aurobindian is good for all seasons". See blog post dated 23 Aug 2006 "Savitri Era is our religion" ... So even if Aurobindonian is grammatically incorrect, it is still the more common adjectival form in print.
