Abstract

If, after a century of analysis there is a turn to synthesis, Hua-Yan and Whitehead will become important resources. Especially given the radical difference of their historical contexts, their similarity is striking, but they differ on time. Whitehead is clear that relations to the future always differ in kind from those to the past, and Theravada Buddhist agree. But Hua-yan is open to a greater symmetry in enlightened experience.
