仁王經疏 1.58

1.58

釋曰：第六、三空觀門德。言三空者，一空門、二無相門、三無願門。薩婆多宗，空無我行名為空門，滅下四行名為無相，餘十種行名為無願，此三亦名三三昧也，依經部宗勘。今依大乘，《佛地論》云「遍計所執生法無我說名為空，緣此三摩地名空解脫門。」相謂十相，即色、聲、香、味、觸、男、女、生、老、死（亦名生、住、滅也），則是涅槃無此等相，故名無相，緣此三摩地名無相解脫門。願謂願求，觀三界苦無所願求，故名無願，緣此三摩地名無願解脫門。《智度論》第六云「知一切法實相，所謂畢竟空，是名空三昧。知是空已，不觀諸法若空不空、若有若無等，是名無作三昧。一切法無有相，一切法不受不著，是名無相三昧。復次十八空，是名空三昧。種種有中心不求，是名無作三昧。一切諸相破壞不憶念，是名無相三昧。」具說如彼。

Explanation: Sixth is the virtue of the contemplation gateway of the three types of emptiness. Regarding the three types of emptiness: first is the emptiness gateway, second is the signless gateway, and third is the wishless gateway. According to the Sarvāstivāda school, the practices of emptiness and non-self are called the emptiness gateway; the four practices under [the truth of] cessation are called the signless; the remaining ten practices are called the wishless; these three are also called the three samādhis, as collated according to the Sautrāntika school. Now, according to the Mahāyāna, the Buddhabhūmi-śāstra states: "The non-self of persons and phenomena that are imagined is called emptiness; the samādhi that takes this as its object is called the emptiness liberation gateway." "Signs" refers to the ten signs: matter, sound, fragrance, taste, touch, male, female, birth, old age, and death (also termed birth, abiding, and cessation); since nirvāṇa lacks these signs, it is called signless; the samādhi that takes this as its object is called the signless liberation gateway. "Wish" refers to aspiring and seeking; contemplating the suffering of the three realms, one has nothing to aspire to or seek, hence it is called wishless; the samādhi that takes this as its object is called the wishless liberation gateway. Fascicle 6 of the Dazhidulun states: "Knowing the true mark of all phenomena, namely ultimate emptiness, is called the emptiness samādhi. Having known this emptiness, not contemplating phenomena as empty or not empty, as existent or non-existent, etc., is called the unconditioned (apraṇihita) samādhi. That all phenomena have no signs, and that one neither accepts nor clings to all phenomena, is called the signless samādhi. Furthermore, the eighteen kinds of emptiness are called the emptiness samādhi. Amidst all varieties of existence, the mind does not seek: this is called the unconditioned samādhi. Shattering all signs and not recollecting them is called the signless samādhi." It is explained in detail as stated there.
