釋禪波羅蜜次第法門 7.68

7.68

八、受諸心行者，此對破根本一心支。今明能通諸法，故名諸心行。心行有二種：一者、動行；二者、不動行。有人解云：從初禪乃至三禪猶是動行，四禪已去，名不動行。今略說不動行者，覺等四支是動行，後一心支是不動行。亦名諸心行者，即是一心支不動之行。若根本禪入一心時，心生染著，此一心不應受。今明受諸心行者，知此一心虛誑不實，一心非心，即不取著，既無過罪，即是三昧正受，故說受諸心行。

Eighth, experiencing mental formations: this corresponds to countering and destroying the fundamental factor of ekāgratā. Now it is clarified that because it can penetrate all dharmas, it is called mental formations. There are two kinds of mental formations: first, active formations; second, inactive formations. Some explain: from the first dhyāna up to the third dhyāna, they are still active formations; from the fourth dhyāna onward, they are called inactive formations. Now, briefly stating the inactive formations: the four factors such as vitarka are active formations, and the subsequent factor of ekāgratā is an inactive formation. It is also called mental formations because it is the inactive formation of the factor of ekāgratā. When entering ekāgratā in the fundamental dhyāna, the mind gives rise to defiled attachment; this ekāgratā should not be experienced. Now clarifying experiencing mental formations: knowing that this ekāgratā is deceptive and unreal, and that ekāgratā is non-mind, one does not grasp or attach; having no faults, it is the correct attainment of samādhi; therefore it is called experiencing mental formations.
