仁王般若經疏 3.24

3.24

“‘Existence is originally devoid of [inherent] nature;
Through causes and conditions all things are accomplished.
That which flourishes must decline;
That which is real must prove hollow.
Sentient beings, teeming and restless,
Are entirely like dwellings in an illusion.
Sound and echo are both empty,
And kingdoms are also like this.’“
