The "Connected Discourses on the Right Efforts" contains discourses focusing on the four right efforts: preventing the arising of unarisen unwholesome states, abandoning arisen unwholesome states, arousing unarisen wholesome states, and maintaining arisen wholesome states. Using vivid similes — such as the Ganges river slanting toward the east — these teachings illustrate how cultivating the right efforts systematically inclines a practitioner toward Nibbāna.
