This handbook explains the procedures and regulation of the Shimotsukie (November ceremony), one of important events of the Tendai Buddhism, held annually at Enryakuji temple. Started by the priest Saicho in 798, the ceremony continues for ten days and involves lectures and discussions on the Lotus sutra. The priest Tenkai worked to reinvigorate the temple, wrote this handbook and thus revived the ceremony, which had been obsolete for more than 70 years.
