Migasālā Sutta
Migasālā Sutta: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.
