10.107

述曰：下次明說六，所以有六義，初明治六障，《對法》、《攝論》所治皆說六蔽，即是六種相違障也。又如《攝大乘》說不發趣因等。以上所言，說十所以：一、十地修行故；二、治十障故；三、證十真如故。此約十地為論，下依六說十，謂：慳悋、犯戒、嗔恚、懈怠、散亂、惡惠，四治相違障故。

The Commentary states: Next is clarifying why six are taught, for which there are six reasons. First is counteracting the six obscurations; the objects of counteraction in the Abhidharma-samuccaya and Mahāyānasaṃgraha are both described as the six hindrances, which are the six kinds of opposing obscurations. Also, as the Mahāyānasaṃgraha speaks of the causes of not setting out, and so forth. What was stated above gives the reasons for teaching ten: first, because of cultivation through the ten stages; second, because of counteracting the ten obscurations; third, because of realizing the ten tathatās. This is discussed in terms of the ten stages; below, ten are explained on the basis of six, namely stinginess, violating precepts, anger, indolence, distraction, and bad wisdom, because the four counteract opposing obscurations.
