Dear Harsha,
I don’t know if a direct link can be demonstrated , but it is notable that, in their cosmological speculations, Adhidharma texts and Mahâyâna sûtras seem also to have become fascinated with large multiples of 10, such as the famous Trisahasra-mahâsahasra,
1000 cubed. The mathematical discovery of how much could be made out of nothing perhaps played a role here.
