I believe that several situations contributed at once. The biggest factor was world war II because after it it was an economic nightmare for the british to continue India as a colony. There was the factor of the restive and therefore increasingly ungovernable Indians. Gandhiji played his role and the violent freedom fighters played their role and both were equally important. Nehru's aura? I don;t know. I think that this was not a contributing factor at all. Nehru contributed only to the partition of India because of his burning desire to quickly become the Prime Minister.
