FYI. In Buddhist epistemology, there are 3 main concepts of the nature of reality. 2 of them are commonly taught around the world and have been for 1,000 to 2,500 years. The other, is only taught in Japan by a group of 50,000 Buddhists although is began in India almost 2,000 years ago. It does out elsewhere. Their systems underscore Zen practice and of the 3, most closely align with modern western thought and psychological research. A man in your line of work might enjoy visit to a place where this is studies and practiced.

As a Zen teacher, I could look into it if you go, but you might do better to ask an Asian Studies professor (I bet you know one) for an English-speaking Hosso Shu Monk. They have famous temples in Kyoto, but they are more religious than philosophical you might do better with their small branch in Tokyo.

BTW. Berkeley used to be a legendary go to source of such information but the culture dumpster fire of American education has ended that tradition, as far as I can see.
