觀無量壽佛經疏 2.58

2.58

八、從勅語內官下，至不令復出已來，明其世王餘瞋禁母。此明世王雖受臣諫放母，猶有餘瞋不令在外。勅語內官閉置深宮，更莫令出與父王相見。

Eighth, from 'He ordered the inner palace officials' down to 'not allowing her to come out again' explains that the king's lingering wrath confined his mother. This explains that although the king accepted his ministers' remonstrance and spared his mother, he still possessed lingering wrath and would not allow her to be outside. He ordered the inner palace officials to shut her away in the deep palace, no longer allowing her to come out to meet with the father-king.
