楞伽阿跋多羅寶經註解 1.697

1.697

彼彼空者，正謂外道所計之空，對此言之，但空於彼而不空此，故云於彼無彼空。譬如鹿子等者，鹿子，人名也，其母毘舍佉優婆夷深重三寶，造立精舍，安止比丘，於中不畜象馬等。言彼舍空者，但無象馬為空，非謂比丘眾亦空。非舍以下，總斥外道邪計之空，謂其縱能空舍比丘，而不能空其二者之性，縱以是處無象馬為空，而餘處非無，是則能所、彼此宛然，何空之有？是名一切法下，結斥之詞，初彼字指外道，但於彼無彼而不能無此。又言七種空內而彼彼空最麆者，是外道之邪計，故誡學者深當遠離也。

Mutual emptiness refers precisely to the emptiness imagined by tīrthikas. Stated in contrast to this, it merely empties that while not emptying this; hence it says 'in that there is no this, and in this there is no that'. When it says 'like Mṛgāra...', Mṛgāra is a person's name; his mother, the upāsikā Viśākhā, deeply revered the Three Jewels and built a monastery to accommodate bhikṣus, where elephants, horses, and the like were not kept. Saying that the mansion is empty means only that it is empty of elephants and horses, not that the assembly of bhikṣus is also empty. From 'it is not that the mansion...' downward, it comprehensively refutes the emptiness falsely imagined by tīrthikas, meaning that even if they can empty the mansion of bhikṣus, they cannot empty the nature of the two; even if they take this place being without elephants and horses as empty, other places are not without them. This being so, the subject and object, that and this, remain fully intact—what emptiness is there? From 'this is called... of all dharmas' downward is a statement of concluding reprimand: the first 'that' refers to the tīrthikas, who merely lack that in this, but cannot be without this. Furthermore, it says that among the seven kinds of emptiness, mutual emptiness is the coarsest because it is the false imagination of tīrthikas; therefore students are admonished to keep far away from it.
