The normal road to the Buddhist ideal after conversion is divided into four successive stages, called the cattāro maggā or 'four paths.'
The first of these is that trodden by the sotāpanno (one 'who has entered the stream' which flows down to the ocean of Nirvana), who is assured of ultimately reaching his goal but has first to undergo seven more existences none of which can be in a state of suffering;
The second path is that trodden by the sakadāgāmī, the disciple whose imperfections have been, so far eradicated that he has only to 'return' to a human-form once more before attaining Nirvana;
The third path is that of the anagāmī, the disciple who will 'not return' to earth, but will attain the goal from a Brahma realm; whilst the fourth and last is Arahatship, which is Nirvana. Each of these four stages is further subdivided into two sub-stages, the lower called 'the path,' and the higher 'the fruit.'
These four cardinal truths of Buddhism are as follows:--(i) individual existence is pain; (ii) cravings cause the continuance of individual existence; (iii) with the disappearance of cravings, individual existence also would disappear; and (iv) cravings disappear by following the Noble Eightfold Path pointed out by the Buddha.
Almsgiving, goodness, renunciation, wisdom, energy, patience, truth, resolution, loving-kindness, and equanimity are the path to Nirvana.
