David Hinton makes the following argument in his book "China Root: On Taoism, Ch'an, and Original Zen" - that when Buddhism arrived in China from India, it was fundamentally reinterpreted and reshaped by Taoist thought, and then the resulting amalgam of Ch'an, or Zen, is so transformed by Taoism that it is scarcely recognizable as Buddhism at all. Our guiding teacher explores this idea in the context of how original Buddhist teachings
combined with Mahayana features such as inherent Buddha nature, interdependence, thusness, "sudden" realization, and radical nondualism to manifest as the Ch'an or Zen that we recognize. A lively discussion follows.
