The Chapter on Coolness
1.
Commentary on the Discourse on Coolness
85. In the first of the ninth, "coolness" means the state of coolness. In the passage beginning with "at the time when the mind should be restrained," at the time of restlessness the mind should be restrained by concentration; at the time fallen into idleness it should be exerted by energy; at the time gone to dullness it should be gladdened by concentration; at the time of even proceeding it should be looked upon with equanimity by the equanimity of the factors of enlightenment.
