I want to know the answer to the following question:
Evidence suggests that many Early mahayana scriptures originated in what part of India?
All the background I'm provided with is that "Anthony Barber and Sree Padma note that "historians of Buddhist thought have been aware for quite some time that such pivotally important Mahayana Buddhist thinkers as Nāgārjuna, Dignaga, Candrakīrti, Āryadeva, and Bhavaviveka, among many others, formulated their theories while living in Buddhist communities in Āndhra.". Is that enough to answer the question?
