Saichō and the Fan Wang Precepts

Saichō clearly advocated strict adherence to the Fan wang precepts. Later attempts to substitute the Lotus Sūtra’s precepts for them were in violation of Saichō’s intention. His only reference in the Kenkairon to the precepts of the Lotus Sūtra concerned the anrakugyō proscription on consorting with Hinayāna practitioners. Saichō thus awarded the Fan wang Ching a higher status than had Chih-i, who relegated it to the status of Kegon teachings, a mixture of Unique and Perfect teachings.
