[190] Then, further, investigating, he investigates: "But this birth (jāti)—what is its source, what is its origin, from what is it born, from what is it produced? When what exists does birth come to be? When what does not exist does birth not come to be?" Investigating, he understands thus: "Birth has existence (bhava) as its source, existence as its origin; it is born from existence, produced from existence. When existence exists, birth comes to be; when existence does not exist, birth does not come to be." He understands birth, he understands the origin of birth, he understands the cessation of birth, and he understands the way of practice (paṭipadā) that is fitting, leading to the cessation of birth; and he is one practicing accordingly, one who conducts himself in accordance with the Dhamma (anudhammacārī). This, bhikkhus, is called a bhikkhu who is practicing for the utterly complete and right destruction of suffering (dukkha), for the cessation of birth.
