The Regulations of the Japanese Sto Sect of Zen Buddhism

It wasn't until 1615 that Ieyasu began trying to issue regulations which covered the entirety of Japan's Buddhist temples. Also absent were smaller sects like the jisek, a type of amidecentric Buddhism where clerics wandered on circuits rather than remaining with specific temples. To become a resident temple abbot, one must have had 30 years of clerical training. Many who have received imperial permission to serve as the abbot of a Heiji or Sōjiji may don a purple robe.
