佛遺教經論疏節要 1.342

1.342

貪著有二：一於真實義處生著，名理障也；二於世間事處生著，名事障也。若有智慧則二著不起，名破障也。

Craving attachment is twofold: first, giving rise to attachment to the real truth, termed the obstacle of principle; second, giving rise to attachment to worldly phenomena, termed the obstacle of phenomena. If one has wisdom, these two attachments do not arise; this is called destroying the obstacles.
