The approach to the teachings of emptiness which I kind of put into my book, our view is actually really quite different than sort of more typical approaches that you find in certainly in the insight meditation tradition. The seed for it came from one of my teachers who I haven't had any contact with for, gosh, almost 20 years, 16 years. Ajahn Tanesara also known as Ajahn Jeff. He was based in San Diego in a monastery that has been a monk for goodness knows 40 years or something probably. From the Thai forest tradition, a particular strand of that tradition, he talked a lot about this idea of fabrication.
