Tassa na tādiso chando hoti adhisīlasikkhāsamādāne seyyathāpi aññesaṁ bhikkhūnaṁ, na tādiso chando hoti adhicittasikkhāsamādāne seyyathāpi aññesaṁ bhikkhūnaṁ, na tādiso chando hoti adhipaññāsikkhāsamādāne seyyathāpi aññesaṁ bhikkhūnaṁ.

And what is the training in the higher wisdom? They truly understand: ‘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 called the training in the higher wisdom. These are the three trainings.” "

And they live having realized it with their own insight due to the ending of defilements. This is called the training in the higher wisdom. These are the three trainings.
