The "four good roots" of the Yoga^ca^ra school. These are present at the final stage of the 'ten dedications of merit' （十回向）. Just at the point of finishing the tenth "dedication，" one cultivates the four views of the fathoming mind， and the four views of absolute reality. In terms of the five stages （五位） this occurs at the second stage （加行位）， 'preparation.' The four roots are 'warmth' （暖）， The 'pinnacle' （顶）， 'forbearance' （忍）， and The 'highest worldly wisdom' （世第一法）.
