The Buddha's words

Nandiyasutta SN 45.10 https://suttacentral.net/sn45.10

At Savatthī. Then the wanderer Nandiya approached the Blessed One and exchanged greetings with him. When they had concluded their greetings and cordial talk, he sat down to one side and said to the Blessed One:

“How many things, Master Gotama, when developed and cultivated, lead to Nibbāna, have Nibbāna as their destination, Nibbāna as their final goal?”

“These eight things, Nandiya, when developed and cultivated, lead to Nibbāna, have Nibbāna as their destination, Nibbāna as their final goal. What eight? Right view, right intention, right speech, right action, right livelihood, right effort, right mindfulness, right concentration. These eight things, when developed and cultivated, lead to Nibbāna, have Nibbāna as their destination, Nibbāna as their final goal.”

When this was said, the wanderer Nandiya said to the Blessed One: “Magnificent, Master Gotama! Magnificent, Master Gotama! Master Gotama has made the Dhamma clear in many ways, as though he were turning upright what had been overturned, revealing what was hidden, showing the way to one who was lost, or holding up a lamp in the dark for those with eyesight to see forms. I go to Master Gotama for refuge and to the Dhamma and to the Sangha of bhikkhus. Let Master Gotama remember me as a lay follower who has gone for refuge for life.”
