At Sāvatthī.

Then a mendicant went up to the Buddha … and asked him, “Sir, they speak of this person called ‘a trainee’. How is a trainee defined?”

“Mendicant, it’s someone who has a trainee’s right view, right thought, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion. That’s how a trainee is defined.”
