Thus I have heard: One time, the Buddha was staying at the Residence of Sages in the Deer Preserve of Bārāṇasī.
It was then that the Bhagavān addressed the monks, “There are four noble truths. What are the four? They are the noble truth of suffering, the noble truth of suffering’s formation, the noble truth of suffering’s cessation, and the noble truth of the path to suffering’s cessation.
“If he has yet to immediately understand these four noble truths, a monk must cultivate that immediate understanding. By producing an increasing desire and applying himself as he is able, he should realize it with right mindfulness and right knowledge.”
After the Buddha spoke this sūtra, the monks who heard what the Buddha taught rejoiced and approved.
