[257] Then, exploring still further, one explores inwardly (antaraṃ sammasaṃ): "But this acquisition (upadhi) — what is its source, what is its origin, from what is it born, from what is it produced? When what exists does acquisition come to be? When what does not exist does acquisition not come to be?" Exploring thus, one knows: "Acquisition has craving (taṇhā) as its source, craving as its origin; it is born from craving, produced from craving. When craving exists, acquisition comes to be; when craving does not exist, acquisition does not come to be." One understands acquisition, one understands the origin of acquisition, one understands the cessation of acquisition, and one understands the way of practice that is appropriate for leading to the cessation of acquisition; and one is practicing accordingly, conducting oneself in conformity with the Dhamma. Bhikkhus, this is called a bhikkhu who is practicing for the entirely complete and right destruction of suffering (dukkha), for the cessation of acquisition.
