Yojana (youxun): (Yojana; meaning a measure of distance. Some other sūtras say that forty li make one yojana. The Abhidharmakośa-śāstra states: the paramāṇu, aṇu, gold dust, water dust, hare hair, sheep hair, ox hair, sunbeam dust, nit, louse, barley grain, and finger joint, each successively increasing by seven times. Twenty-four fingers make a cubit [hastakā]; four cubits make a bow's length [dhanus]; five hundred bows make one krośa; eight krośas make one yojana, which is over sixteen and a half li).
