大般涅槃經義記 3.256

3.256

In the second pair, first harm, then benefit. In the harm: 'if one cultivates the Tathāgata's hidden garbha as non-self and empty and tranquil' recapitulates the aforementioned delusion; grasping that principle of emptiness as the tathāgatagarbha is called cultivating the hidden garbha as non-self and empty. 'For immeasurable eons transmigrating and undergoing suffering in birth and death' directly clarifies that there is harm; grasping emptiness and slandering reality leads to being in birth and death, which is called undergoing various sufferings. In the benefit: 'if one does not do so' recapitulates the aforementioned awakening; turning away from emptiness to seek the real is called 'not doing so'; 'if there is affliction, it is quickly eliminated' directly clarifies that there is benefit. The explanation begins from 'Why?': because by knowing the garbha, one thoroughly realizes that delusion is originally non-existent, and therefore quickly eliminates affliction.
