This was said by the Blessed One, said by the Arahant, as I have heard:

"Bhikkhus, there are these three quests. What three? The quest for sensual pleasure, the quest for renewed existence, and the quest for spiritual life. These are the three quests."

The Blessed One spoke on this matter. In this regard, it is said:

"Collected and fully aware, the mindful disciple of the Buddha; Understands quests, and the source of quests.

Where these [quests] cease, and the way of practice leading to their cessation; With the cessation of quests, the bhikkhu, is satiated and completely quenched [of mental defilements]."

This matter too was spoken by the Blessed One, as I have heard.
