We introduce satipaṭṭhāna, the way of mindfulness. More than just a meditation technique, satipaṭṭhāna represents a way of practice that is a “one-way street” (ekāyana magga) leading direct to nibbāna. We examine the meaning of nibbāna, looking at it both cognitively and affectively. And we discuss the relationship between the practice of tracking experience over time, and nibbāna itself.
