I have encountered another fascinating Agama sutra without a Pali parallel that involves a Buddhist encounter with a brahmin. In this case, it is EA 16.9. Aniruddha is reverenced by a large assembly of spirits and gods. A brahmin happens by and notices the fragrance of the gods but can’t see them, so he asked Aniruddha about it. Aniruddha informs him about the gods present, which can’t be seen without the heavenly eye.
Aniruddha proceeds to convert the brahmin to Buddhism with the promise of the complete vision gained by the unsurpassed wisdom eye. He says that it surpasses even the vision of Brahma “Thousand Eyes” who sees all of his thousand-world realm at once but can’t see himself. The brahmin questions Aniruddha about this and his Dharma eye opens shortly after leaving while he thought about what Aniruddha had told him.
My question for those more knowledgeable about the Vedic literature is: What is the chronology of this concept of Brahma having a thousand eyes?
I’ve noticed there is also a tradition ascribing a thousand eyes to Indra as well, but there’s not much I can find about Brahma having a thousand eyes. Also, in this Buddhist sutra, “Thousand Eyes” is this Brahma’s name, not just an attribute that he possesses.
