仁王護國般若波羅蜜多經疏 2.108

2.108

解曰：若有修習般若等者，謂若說聽亡說聽相。譬如等者，舉喻明也，兩句喻人、兩句喻法。譬如幻士者，幻化之士或如木人，彼雖轉動，無主宰故；觀身如幻，雖有說聽亡說聽相，不分別故。法同法性猶如虛空者，上言法者，所有悟解理事之法。同法性者，即真如也。於所悟解熾然修行，了相即性如虛空故。從此第二結人法空。

The commentary explains: 'If anyone cultivates prajñā...' means that if one speaks or listens, one forgets the marks of speaking and listening. 'Like...' uses metaphors to clarify: two lines illustrate the persons, and two lines illustrate the dharmas. 'Like illusory people': illusory people are like wooden automatons; though they move, they have no master. Contemplating the body as illusory, though there is speaking and listening, one forgets the marks of speaking and listening because one does not discriminate. 'The dharmas are identical to the dharmatā, just like empty space': 'dharmas' above refers to all understood dharmas of principle and phenomena. 'Identical to the dharmatā' refers to tathatā. One vigorously practices what has been understood, realizing that characteristics are identical to nature, just like empty space. Next is the second section, concluding the emptiness of persons and dharmas.
