Can anyone share or tell: where can I find a summary explaining those ancient Indian philosophies of those non-Buddhist schools that had debated with Buddhist, especially Nalanda, masters? For example, those philosophies of those opponents in Indian Buddhism Śāstras (i.e. treaties).
I ask because I am studying some texts on and also pondering on the tenets system/theory of Indian Buddhism, and I would like to be rigorous in understanding what non-Buddhist philosophies are refuted grounding in reasoning by Indian Buddhism (Nalanda) masters.
