仁王般若經疏 2.115

2.115

「有無本自二，譬如牛二角，照解見無二，二諦常不即。解心見不二，求二不可得，非謂二諦一，非二何可得？於解常自一，於諦常自二，通達此無二，真入第一義。」

"Existence and non-existence are originally two,
just like the two horns of an ox;
illumined understanding sees non-duality,
yet the two truths are ever not identical.
When the understanding mind sees non-duality,
seeking duality, it cannot be found;
it is not that the two truths are one,
yet if not two, how could [one] be found?
In understanding, it is ever naturally one;
in truth, it is ever naturally two;
one who penetrates this non-duality
truly enters the ultimate truth."
