大乘百法明門論開宗義決 1.149

1.149

遠離麁重調暢身心等者。麁重有二。一者二障。二者種子。立麁重名。性無堪任違細輕故。二者二障種子所引身中無堪任性。此與五蘊不一不異。而離五蘊無別自性。此令身心惛昧沈重無所安和。違細輕故亦名麁重。今此文中所遠離者說後非前。

Regarding "distancing oneself from dauṣṭhulya, harmonizing body and mind, and so forth": dauṣṭhulya is of two kinds: first, the twofold obscuration; second, the seeds. They are established with the name dauṣṭhulya because their nature lacks competence and opposes lightness and pliancy. Second, the incompetence within the body induced by the seeds of the twofold obscuration; this is neither identical to nor different from the five aggregates, yet apart from the five aggregates it has no separate self-nature. This causes body and mind to be dim, heavy, and without peace and harmony; because it opposes lightness and pliancy, it is also called dauṣṭhulya. What is distanced here in this text refers to the latter, not the former.
