三界
Trailokya or Triloka; the three realms; also 三有. It is the Buddhist metaphysical equivalent for the Brahmanic cosmological bhuvanatraya, or triple world of bhr, bhuva, and svar, earth, atmosphere, and heaven. The Buddhist three are 欲, 色, and 无色界, i.e. world of sensuous desire, form, and formless world of pure spirit. (a) 欲界 Kmadhtu is the realm of sensuous desire, of 淫 and 食 sex and food; it includes the six heavens of desire, the human world, and the hells. (b) 色界 Rpadhtu is the realm of form, meaning 质碍 that which is substantial and resistant: it is above the lust-world and contains (so to speak) bodies, palaces, things, all mystic and wonderful一a semi-material conception like that in Revelation; it is represented in the 四禅天, or Brahmalokas. (c) 无色界 Arpadhtu, or rpyadhtu, is the formless realm of pure spirit, where there are no bodies, places, things, at any rate none to which human terms would apply, but where the mind dwells in mystic contemplation; its extent is indefinable, but it is, conceived of in four stages, i,e. 四空处 the four "empty" regions, or regions of space in the immaterial world, which are 四无色 the four "formless" realms, or realms beyond form; being above the realm of form, their bounds cannot be defined. v. 舍论世间品.The sick-bed of the trailokya, especially this world of suffering.
