The Noble Sūtra “The Inquiry of Lokadhara”

In The Inquiry of Lokadhara, the bodhisattva Lokadhara asks the Buddha to explain the proper way for bodhisattvas to discern the characteristics of phenomena and employ that knowledge to attain awakening. In reply, the Buddha teaches at length how to understand the lack of inherent existence of phenomena. As part of the teaching, the Buddha explains in detail the nonexistence of the aggregates, the elements, the sense sources, dependently originated phenomena, the four applications of mindfulness, the five powers, the eightfold path of the noble ones, and mundane and transcendent phenomena, as well as conditioned and unconditioned phenomena.
