This afternoon Alan leads a guided meditation [6:25] that integrates the three different methods of vipashyana as taught by Padmasambhava. After the guided meditation [31:40], Alan talks about the history and development of science by answering the following questions: 1. When did the different schools and interpretations of scientific discovery occur? 2. How did natural philosophy develop into science? 3, How did scientific materialism occur? 4. When did scientific materialism become state religion? 5. Do all branches of science share the same worldview?
