So I have heard. At one time the Buddha was staying near Kosambī in Ghosita’s monastery. There the Buddha addressed the mendicants: “Mendicants, is there a way that a mendicant who is a trainee, standing at the level of a trainee, can understand that they are a trainee? And that a mendicant who is an adept, standing at the level of an adept, can understand that they are an adept?”

“Our teachings are rooted in the Buddha. …” “There is a way that a mendicant who is a trainee, standing at the level of a trainee, can understand that they are a trainee, and that a mendicant who is an adept, standing at the level of an adept, can understand that they are an adept.

And what is a way that a mendicant who is a trainee can understand that they are a trainee? It’s when a mendicant who is a trainee truly understands: ‘This is suffering’ … ‘This is the origin of suffering’ … ‘This is the cessation of suffering’ … ‘This is the practice that leads to the cessation of suffering’. This is a way that a mendicant who is a trainee can understand that they are a trainee.
