In this teaching Rinpoche presents the main schools of Buddhist philosophy with their progressively more subtle and refined views of reality. However it is not just a teaching on the view, but a presentation providing the student the means to realize it through meditation practice. The idea of a series of meditation practices on a particular aspect of the Buddha's teaching is that beginning with one's first rather coarse commonsense understanding, one progresses through increasingly subtle and more refined stages until one arrives at complete and perfect understanding. Each stage in the process prepares the mind for the next in so far as each step is fully integrated into one's understanding through the meditation process.
