Dhamma attributes (6): Paccattam Veditabbo

Under this attribute, three types of ariyas should be noted, namely,

(i) the Uggahaṭitaññū, one who attains magga-phala after hearing the gist of a discourse on the Dhamma,
(ii) the Vipacitaññū, one who realizes magga-phala after hearing an explanation of the Dhamma, and
(iii) the Neyya, one who gradually comes to comprehend the truth after getting further elaboration and guidance.

All the three types, after attaining the Path, know for themselves that they have taken up the Noble Practice, that they have attained the Path, the Fruition, and have realized Nibbāna through their own experience. For the eradication of defilements is to be accomplished directly by oneself. A close disciple cannot discard his defilements through the attainment of the Path by his master. Nor can he dwell in the Fruition of the Path through the attainment of the Fruition by his master. Neither can he make Nibbāna his own mind-object through the master’s making Nibbāna his (the master's) mind-object. Only by the attainment of magga by one’s ownself, can one get rid of the defilements within oneself. Dwelling in the Fruition is possible only when one has attained the Fruition-Knowledge by oneself. Nibbāna also is likewise a matter for direct experience, and not realizable through another’s experience. Thus, the nine Supramundane factors are not to be considered as ornaments that adorn other people (and have no real benefit to oneself) but are only the property of the ariyas who only can enjoy them. Since they pertain to the wise, these factors are beyond the pale of fools.

Thus the nine supramundane factors are the property of the ariyas who alone can realize them in their mind and enjoy them, paccattaṃ-veditabbo.
