[113] And what, bhikkhus, is form (rūpa)? The four great elements (mahābhūta) and the form derived from (upādāya) the four great elements: this, bhikkhus, is called form. With the origin of nutriment (āhāra) there is the origin of form; with the cessation of nutriment there is the cessation of form. This very Noble Eightfold Path is the way of practice leading to the cessation of form, namely: right view … right concentration (samādhi).
Bhikkhus, whatever ascetics or brahmins, having directly known form thus, having directly known the origin of form thus, having directly known the cessation of form thus, having directly known the way of practice leading to the cessation of form thus, are practising for the purpose of disenchantment with form, for its dispassion, for its cessation — they are practising well. Those who are practising well have gained a footing in this Dhamma and Discipline.
And, bhikkhus, whatever ascetics or brahmins, having directly known form thus, having directly known the origin of form thus, having directly known the cessation of form thus, having directly known the way of practice leading to the cessation of form thus, are liberated through non-clinging, by means of disenchantment with form, by dispassion, by cessation — they are well liberated. Those who are well liberated are consummate ones (kevalino). For those who are consummate ones, there is no round (vaṭṭa) whereby they might be described.
