Ananda visits Migasālā in her home and is questioned as to why both Pūrana and Isidatta, the former of whom was a brahmacārī and the latter not, should both have been born in Tusita, as sakadāgāmins. Ananda offers no explanation, but consults the Buddha, who declares that Migasālā is but a foolish, frail, motherly body with none but mother wit; how, then, could she understand the diversity in the person of man? (purisa-puggala-paropariyañāna). The Buddha then goes on to divide men into six classes according to their capabilities and attainments. It is not possible for anyone, save a Tathāgata, to measure persons. A.iii.347ff.; v. 137ff.
