「道」亦依其修习为一种。依止、观之别或依见、修之别为二种。依（戒、定、慧）三蕴之别为三种。因为此道有（八）部分之故，可以三蕴而包摄，犹如都市包摄于国内。即所谓：

Ñ(XVI,95): Also the path is of one kind as what should be developed. It is of two kinds classed according to serenity and insight, or classed according to seeing and developing. It is of three kinds classed according to the three aggregates; for the [path], being selective, is included by the three aggregates, which are comprehensive, as a city is by a kingdom, according as it is said: 

‘‘Na kho, āvuso visākha, ariyena aṭṭhaṅgikena maggena tayo khandhā saṅgahitā, tīhi ca kho, āvuso visākha, khandhehi ariyo aṭṭhaṅgiko maggo saṅgahito. Yā cāvuso visākha, sammāvācā, yo ca sammākammanto, yo ca sammāājīvo, ime dhammā sīlakkhandhe saṅgahitā. Yo ca sammāvāyāmo, yā ca sammāsati, yo ca sammāsamādhi, ime dhammā samādhikkhandhe saṅgahitā. Yā ca sammādiṭṭhi, yo ca sammāsaṅkappo, ime dhammā paññākkhandhe saṅgahitā’’ti (ma. ni. 1.462).

「朋友，毗舍佉，不是以八支圣道而包摄三蕴。朋友，毗舍佉，以三蕴而包摄八支圣道。朋友，毗舍佉，正语、正业、正命的三法包摄于戒蕴中。正精进、正念、正定的三法包摄于定蕴中。正见、正思惟的二法包摄于慧蕴中」。

Ñ: 'The three aggregates are not included in the Noble Eightfold Path, friend Visākha, but the Noble Eightfold Path is included by the three aggregates. Any right speech, any right action, any right livelihood: these are included in the virtue aggregate. Any right effort, any right mindfulness, any right concentration: these are included in the concentration aggregate. Any right view, any right thinking: these are included in the understanding aggregate' (M.i,301).
