In this video Vince Fakhoury Horn explores the evolution of Buddhism through four major phases or "turnings". He explains how the original teachings of the Buddha in the first turning were built upon in subsequent turnings, with the second turning emphasizing emptiness and the Bodhisattva path, the third turning introducing concepts like Buddha-nature, and the fourth turning integrating Eastern enlightenment with Western enlightenment, where Vince argues that a legitimate fourth turning tradition would recognize the importance of waking up, cleaning up, growing up, and showing up.
