金剛般若經贊述 2.41

2.41

述曰，此第二遣外執也。「如來所得法」者，謂所證理。「無實」者，謂不可如言而取實。「無虛」者，亦不可離言而別求。由不虛故，依佛教修學；由不實故，離妄想而證真也。謂凡夫妄想所執無有故不實，如來無妄想說故不虛也。

The commentary says: This second [part] dispels external attachments. "The Dharma attained by the Tathāgata" refers to the principle realized. "Neither real" means that it cannot be grasped as real according to words. "Nor unreal" means that it also cannot be sought separately apart from words. Because it is not unreal, one cultivates and learns in reliance on the Buddha's teaching; because it is not real, one leaves behind false conceptualization and realizes the true. That is to say, because what ordinary beings grasp through false conceptualization does not exist, it is not real; because the Tathāgata speaks free of false conceptualization, it is not unreal.
