There are many unknown points about the date of completion of the Zaija kōshoshū 摧邪興正集, and the identity of its compiler Jitsue 実恵.
Jitsue says: Teachings of the Pure Land are not the cause of hell, they are the domain of the roots of good of the Mahāyāna. They are the country of the pure purity of the One Vehicle. To chant the name of Amitābha Buddha is a practice of the great wisdom of the Mahāyāna. They are the domain of the Ultimate One Vehicle.
The assertions of the Zaija kōshoshū are largely based on the doctrines of Shandao 善導.
