仁王般若經疏 3.188

3.188

From "At that time, the sixteen [great] kings" onward is the third major section of the chapter: the various kings hear the Buddha's seven admonitions and do not regulate the fourfold assembly. In the text there are two [parts]: first, the sixteen kings grieve, sigh, and are terrified, lamenting their past errors, and following the teachings they do not regulate the fourfold assembly. Second, the eighteen Brahmā kings and others lament and sigh, saying that at that time the world will be empty and desolate, an age without a Buddha; this laments that the correct Dharma will have perished completely, hence it is called "an age without a Buddha."
