金剛經纂要刊定記 2.32

2.32

"Doubt" means being hesitant and undecided regarding principle and phenomena; it is one of the afflictions among mental factors. There are two kinds: first, seeds; second, manifest activity. "Seeds" refers to what is stored in the storehouse consciousness and has not yet become manifest, called "unrisen". "Manifest activity" refers to what stirs in the mind or takes shape in speech, called "presently arisen". "To prevent" means to prevent the seeds, not allowing them to arise into manifest activity. "To sever" means to sever manifest activity, thereby naturally eliminating its root. It is like building a dike to hold back water, or pouring water to douse flames; the meaning is evident.
