三彌勒經疏 1.181

1.181

經曰「又彌勒如來」以下，第三迦葉衣上彌勒。此中二：初彌勒示彰、後彌勒受衣。是初也。鬼神開門者，《智度論》云「彌勒佛以足指扣開耆闍崛山，時迦葉骨身著僧伽梨而出，禮彌勒足，上昇虛空，現變如前，即於空滅身。」然此經中鬼開者，鬼神從佛行故，故不違也。釋迦禪窟者，《阿含經》云「迦葉靜窟」。解云：年舉者，古時釋迦禪室故。又可此經誤也。得法眼淨者，善根已熟者也。或有眾生者，未熟善根，故不得聖果，唯見迦葉骨身也。亦由四事因緣者，由釋迦四攝事所成熟，謂：一惠施，即此施也。二愛語，即此仁愛也。三利行，則此利人。四等利，即此亦同。《善生經》如是說。

From the sūtra saying "Furthermore, Maitreya Tathāgata..." onward is the third part, Kāśyapa offering the robe to Maitreya. Here there are two parts: first, Maitreya demonstrates and reveals it; second, Maitreya receives the robe. This is the first part. Regarding "spirits opening the gate," the Da zhidu lun says: "The Buddha Maitreya tapped and opened Mount Gṛdhrakūṭa with his toe. At that time, Kāśyapa's skeleton-body emerged wearing the saṅghāṭī, bowed at Maitreya's feet, ascended into empty space, manifested transformations as before, and extinguished his body right in the sky." However, in this sūtra, the opening by spirits is because the spirits follow the Buddha; hence there is no contradiction. Regarding "Śākya's meditation cave," the Āgama says "Kāśyapa's quiet cave." It is explained: "Naming the age" refers to what was of old Śākyamuni's meditation chamber. Alternatively, this sūtra may contain an error. Those who "attained purity of the Dharma eye" are those whose wholesome roots had already matured. "Some sentient beings" are those whose wholesome roots were not yet mature; hence they did not attain the noble fruit, but merely saw Kāśyapa's skeleton-body. "Also due to the causes and conditions of the four bases" means being matured by Śākyamuni's four bases of benevolence: first, giving, which is this generosity; second, affectionate speech, which is this benevolence; third, beneficial action, which is this benefiting of people; fourth, shared benefit, which is also identical. The Sigālovāda Sūtra speaks thus.
