12.8

The commentary says: With the paramāṇu as the first and the finger-joint as the last, one should know that each subsequent increases sevenfold: seven paramāṇus make the measure of one aṇu; accumulating aṇus to seven makes one speck of gold-dust (one explanation says: a dust speck resting on gold; another explanation says: a dust speck passing through gold; up to water-dust below there are two interpretations for each); accumulating seven specks of gold-dust makes one speck of water-dust; accumulating seven specks of water-dust makes one hare-hair dust speck (one explanation: resting on a hare's hair; one explanation: of the size of the tip of a hare's hair; up to cow-hair, there are two interpretations for each); accumulating seven hare-hair dust specks makes one sheep-hair dust speck; accumulating seven sheep-hair dust specks makes one cow-hair dust speck; accumulating seven cow-hair dust specks makes one dust speck floating in a crack (crevice-dust); accumulating seven crevice-dust specks makes one nit; accumulating seven nits makes one louse; accumulating seven lice makes one barley-grain; accumulating seven barley-grains makes one finger-joint; three joints make one finger; twenty-four fingers laid crosswise make one forearm (hasta); four forearms stacked vertically make one bow (dhanus), meaning an arm-span; five hundred bows stacked vertically make one krośa. One krośa is calculated as the distance on a road from a village to an araṇya (translated here as 'free from clamour'). Eight krośas are said to make one yojana. (The explanation says: one forearm is calculated as one chi and eight cun, one bow as seven chi and two cun, up to one krośa calculated as two li, and one yojana as sixteen li).
