18.22

In stating the number: [Commentary:] "Four indestructible faiths" means placing faith in those four matters as all being indestructible; indestructible means eternally abiding. Because the objects of faith are indestructible, they cause the mind that has faith to also be indestructible. Subject and object correspond to each other, and both are called indestructible. Thus a sūtra says: "Wondrous faith is eternally abiding"; this is it.
