觀無量壽佛經疏 2.58

2.58

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.
