仁王經疏 2.87

2.87

釋曰：第二、正辨除障。於前位中已斷色心二種麁習，今此位中亦斷色心二種細習。為顯所斷最微細故，但名心習。

Explanation: Second, directly discerning the elimination of obstacles. In the preceding stages, both coarse propensities of form and mind had already been severed; now, in this stage, both subtle propensities of form and mind are also severed. To show that what is severed is the most subtle, it is merely called "mental propensities."
