6.p86

“What is a monk’s well-being and happiness? Here, a monk abandons lust and departs from unskillful qualities. With perception and examination, his seclusion gives rise to joy and happiness, and he practices the first dhyāna. Without perception or examination, his samādhi gives rise to joy and happiness, and he practices the second dhyāna. He abandons joy, remains mindful, focuses his mind, and isn’t distracted. He knows his own happiness is what’s sought by noble people. He’s mindful and lives happily, practicing the third dhyāna. He abandons and ceases pain and pleasure, ridding himself of his earlier sadness and joy. Not discomforted or pleased, he’s carefully mindful and pure and practices the fourth dhyāna. This is a monk’s well-being and happiness.
