Yojana (踰繕那: the first character has the fanqie *y- / zh-*; shan 繕 is pronounced shan 善; this is Sanskrit; formerly rendered youxun 由旬, or youyan 由延, or yuzhena 踰闍那, which are all corrupt abbreviations. According to the Record of the Western Regions: "A yojana has been, since ancient times, the day's march of a sacred king's army. The old tradition held that one yojana is forty li. The common custom in India is thirty li. What is recorded in the sacred teachings is only sixteen li. When examining these differing accounts, each has its basis: some take the time of a sacred king's march, some take measurements in cubits, and some take ancient feet; ultimately it is one day's march for an army." Now one should properly follow the Record of the Western Regions, fixing it at thirty li. For Master Xuanzang personally investigated the distances and compiled this travel record in response to the inquiries of Emperor Taizong, so it can truly be relied upon. This is all explained according to the glosses of Master Huilin and Master Ci'en).
