楞伽阿跋多羅寶經註解 1.20

1.20

此離惑、智二障。煩惱，惑障也；爾焰乃梵語，智障也。智本破惑，惑即人法二執。無我者，無此二執也。若於智生著，智亦成障。如來了知人法惑智本空，故云「常清淨無相」。眾生在迷受苦，故起悲心而拔濟之。

This is freedom from the two obstacles of delusion and knowledge. Afflictions are the obstacle of delusion; 'eryan' (jñeya) is a Sanskrit word meaning the obstacle of knowledge. Wisdom originally shatters delusion; delusion is the two attachments to person and dharmas. 'Selflessness' means the absence of these two attachments. If one produces attachment toward wisdom, wisdom also becomes an obstacle. The Tathāgata fully realizes that both persons and dharmas, delusion and wisdom, are fundamentally empty; hence it is said, 'constantly pure and markless.' Because sentient beings suffer in confusion, he gives rise to a mind of compassion to rescue and deliver them.
