“There are another five things, which are five kinds of joy from entering liberation: If a monk is diligent and not negligent, happily lives in seclusion, focuses his attention, and unifies his mind, he’ll understand what he doesn’t yet understand, end what he hasn’t yet ended, and become peaceful where he isn’t yet peaceful. What are the five? [1] Here, a monk hears the Tathāgata teach the Dharma, hears a religious practitioner teach it, or hears a senior teacher teach the Dharma. He contemplates, investigates, and discerns the meaning of that Dharma, and his mind becomes joyous. After his mind becomes joyous, he attains the love of Dharma. After he attains the love of Dharma, he’s comfortable in body and mind. After he’s comfortable in body and mind, then he attains the samādhi of dhyāna. After he attains the samādhi of dhyāna, he attains true knowing and seeing. This is the first way to enter liberation.
