楞伽阿跋多羅寶經註解 1.685

1.685

此徵釋相空。而言一切性自共相空者，蓋一切法本無自、他、共、離四性，眾生妄執從四性生。四性即四句，四句求其生相了不可得，故云相空。展轉積聚者，即陰界入互相待對也。分別無性者，即分析推求皆無自性。無性亦無，故云相不生也。自他俱性無性者，此覆疎上義，自謂自生、他謂他生、俱謂共生、無謂無因生，無因生即離生也。相不住，即不住於相也。

This questions and explains the emptiness of characteristics. When it says 'the individual and general characteristics of all natures are empty', it is because all dharmas originally lack the four natures of self, other, both, and separated [causes], yet sentient beings falsely grasp them as arising from the four natures. The four natures are the four alternatives; seeking the marks of their arising through the four alternatives, nothing at all can be found, hence it is called 'emptiness of characteristics'. 'Mutually accumulated' refers to the aggregates, realms, and bases mutually depending on one another. 'Upon discrimination there is no nature' means that upon analysis and investigation, none have any self-nature. There being no nature, they are non-existent, hence it says 'characteristics do not arise'. 'The natures of self, other, and both have no nature' explains the above meaning again: 'self' means arising from self, 'other' means arising from other, 'both' means arising from both, and 'no [nature]' means arising without a cause; arising without a cause is just freedom from arising. 'Characteristics do not abide' means not abiding in characteristics.
