次三毒而辨五蓋者，若論三毒之體，豈異五蓋？但科目不同，名字增減有異，故次分別。所以然者，若沒癡毒之名而離癡法，為睡眠、掉悔、疑三蓋，足貪、瞋為五蓋也。若開五蓋則煩惱無量。通名蓋者，蓋以覆蓋為義，能覆蓋行者清淨善心不得開發，故名為蓋。而此五蓋既的為在下所明諸禪正障，故須略辨其相。

The reason why the five hindrances are distinguished after the three poisons is this: when discussing the essence of the three poisons, how could it be different from the five hindrances? It is only that the categories differ and the additions or subtractions of names are distinct, which is why they are differentiated next. Why is this? If one subsumes the name of the poison of delusion and divides the dharma of delusion into the three hindrances of sleep, restlessness and remorse, and doubt, and adds greed and anger, they make the five hindrances. If one opens up the five hindrances, afflictions are immeasurable. They are collectively called 'hindrances' (nīvaraṇa) because hindrance means covering; they can cover the practitioner's pure and wholesome mind so that it cannot unfold, and hence are called hindrances. And since these five hindrances are precisely the primary obstacles to the various dhyānas explained below, their characteristics must be briefly distinguished.
