The Seizan school traces its origins to
Shōkū, a prominent disciple of
Hōnen, who studied and systematized Pure Land doctrine of
Hōnen with an emphasis on faith,
other-power and the
non-duality of Amida and sentient beings. Seizan Jōdo-shū was also influenced by the
Tendai and
Shingon traditions due to the background of its early teachers. One of the key locations for Seizan Jōdo-shū’s development was
Eikan-dō Zenrin-ji, which was originally a
Shingon temple. Jōhen (静遍), one of its abbots, took an interest in Jōdo Buddhism initially as a means to criticize it. However, he later designated Hōnen as the 11th chief priest of Eikan-dō. Afterward, Shōkū became the head priest and officially converted the temple into a Jōdo institution, establishing the temple as a Seizan branch of
Jōdo-shū. Among them, four lineages were particularly influential: Thus, unlike some of Hōnen’s disciples, such as
Kōsai, who rejected all practices except the nembutsu, Seizan Jōdo-shū acknowledges the merit of other Buddhist practices. However, it ranks them in a hierarchy where nembutsu is the foremost practice, similar to how the Shingon, Tendai, and Kegon traditions organize their teachings. While other practices contain some merit, they are not considered equal to even a single recitation of the nembutsu. The core teaching of the
Anjin Ketsujō Shō is that, due to Amida Buddha’s boundless Vow, both Amida’s attainment of Buddhahood and the practitioner's birth in the Pure Land occur simultaneously in a timeless,
non-dual reality. Since this realization has already been accomplished through Amida’s power, self-powered practices are unnecessary. Instead, reciting the
nembutsu serves as an expression of this truth and an awakening to the liberation already granted by Amida. Any attempt to attain Buddhahood through personal effort is seen as futile; all that is required is absolute trust in Amida Buddha through
nembutsu recitation. ==References==
