(1) A Ugghatitannu : an individual who

• encounters a Buddha in person, and
• who is capable of attaining the Holy Paths and the Holy Fruits through the mere hearing of a short concise discourse.

(2) A Vipancitannu: an individual who

• encounters a Buddha in person, but

• who is capable of attaining the Paths and the Fruits only when the short discourse is expounded to him at some length.

(3) A Neyya : an individual who needs

• to study the sermon and the exposition, and then
• to practise the provisions contained therein for 7 days to 60 years, to attain the Paths and the Fruits during this lifetime if he tries hard with guidance from the right teacher.

(4) A Padaparama : is an individual who

• cannot attain the Paths and the Fruits within this lifetime.
• can attain release from worldly ills in his next existence if he dies while practising samatha or vipassana and attains rebirth either as a human being or a deva within the present Buddha Sasana.

Neyya-puggala

An individual of the Neyya class can become a Sotpanna in this present life, if he faithfully practises the bodhipakkhiya-dhamma comprising satipatthana (four Applications of Mindfulness), sammapadhana (Right Exertion), etc. If he is lax in his practice, he can become a Sotapanna only in his next existence after being reborn in the deva planes. If he dies while still aloof from these (bodhipakkhiya-Dhammas) he will become a total loss so far as the present Buddha Sasana is concerned, but he can still attain release from worldly ills if he encounters the Sasana of the next Buddha.

Padaparama-puggala

An individual of the Padaparama class can attain release only within the present Buddha Sasana after rebirth in the deva planes in his next existence, if he can faithfully practise the bodhipakkhiya-Dhammas in his present existence. The present Buddha Sasana will continue to exist so long as the Tipitakas remain in the world. The Padaparama class of individuals have to accumlate as much of the nuclei or seeds of Parami as they can within this lifetime.
