With Poṭṭhapāda 1.39

1.39

‘The following three modes of personality, are common Poṭṭhapāda, (are commonly acknowledged in the world): material, immaterial, and formless. The first has form, is made up of the four elements, and is nourished by solid food. The second has no form, is made up of mind, has all its greater and lesser limbs complete, and all the organs perfect. The third is without form, and is made up of consciousness only.
40-42. ‘Now I teach a doctrine, Poṭṭhapāda, with respect to each of these, that leads to the putting off of that personality; so that, if you walk according to that doctrine, the evil dispositions one has acquired may be put away ; the dispositions which tend to purification may increase; and one may continue to see face to face, and by himself come to realise, the full perfection and grandeur of wisdom.
‘Now it may well be, Poṭṭhapāda, that you think Evil dispositions may be put away, the dispositions that, tend to purification may increase, one may continue to see face to face, and by himself come to realise, the full perfection and grandeur of wisdom, but one may continue sad.” Now that, Poṭṭhapāda, would not be accurate judgement. When such conditions are fulfilled, then there will be joy, and happiness, and peace, and in continual mindfulness and self. mastery, one will dwell at ease.
43-45. ‘And outsiders, Poṭṭhapāda, might question, us thus: “What then, Sir, is that material (or that mental, or, that formless) mode of personality for the putting away of which you preach such a doctrine as will lead him who walks according to it to get free from the evil dispositions he has acquired, to increase in the dispositions that tend to purification, so that he may continue to see face to face, and by himself come to realise, the full perfection and grandeur of wisdom?” And to that I should reply (describing it in the words I have now used to you ). “Why this very personality that you see before you is what I mean.”
‘Now what think you of that, Poṭṭhapāda. That being so, would not the talk turn out to be well grounded?’
‘For a truth, Sir, it would.’
