This talk by Peter Carlson thoroughly summarizes the last verse of the Satipatthana Sutta, the Four Foundations of Mindfulness Discourse, which describes how the Four Noble Truths are transformed by the effective coordinated functioning of the Seven Awakening Factors from a conceptual understanding to direct knowledge of the transient and impersonal nature of subjective experience.  Within the Wisdom Aggregate of the Noble Eightfold Path, Right Understanding is directly realized, becoming Right Knowledge and Right Intention is directly realized, becoming Right Release; in this way, the Noble Eightfold Path becomes the Noble Tenfold Path.  The talk also includes a review of the concept of Nirvana, which, in the Theravaden Buddhist tradition, must be experienced 4 times to achieve full Awakening.

Here are the notes prepared for this talk:  Realizing the Noble Eightfold Path
