Zokushu is the earliest known Buddhist adaptation of the kuji. It is a kuji ritual based on Kakuban's formula, in which each of the kuji corresponds to a shuji/bonji/bija. However, instead of the original nine Taoist syllables, Kakuban created a new set of nine syllables based on the mantra of Amida Nyorai.
