菩薩從兜術天降神母胎說廣普經 4.38

4.38

佛告無盡意：「諦聽！善思念之！今當與汝一一分別。過去九十一劫有梵天王，名大辯才，分別古今常樂閑居坐天宮內。『今我寧可化此宮女及諸梵天，我得成佛諸天翼從，剃鬚髮著法服，一時成道，不亦快乎？』作是念已，即於天宮詣晝度樹，端坐思惟一意一心，繫念在前無他異想，即得成佛，三十二大人相八十種隨形好。諸天眷屬修行比丘正法，得阿羅漢，皆是利根；彼天女眾有得須陀洹、斯陀含、阿那含，不往還此間，即於彼般涅槃。是謂梵天王不捨身、受身、現身得成佛道。」

The Buddha told Akṣayamati: "Listen attentively, and reflect on it well! Now I will distinguish it for you one by one. Ninety-one kalpas ago, there was a Brahmā king named Mahāpratibhāna. He discerned the past and the present, constantly took pleasure in leisure, and sat within his heavenly palace. [He thought:] 'Now, could I not transform these palace maidens and all the Brahmā devas, so that when I attain Buddhahood, the devas will attend me, shaving their beards and hair, donning the Dharma robes, and all together attaining the path at once—would that not be delightful?' Having had this thought, he went from the heavenly palace to the Pārijāta tree, sat upright and reflected with one mind and single focus, tying his mindfulness before him without any other thoughts, and immediately attained Buddhahood, complete with the thirty-two marks of a great man and the eighty secondary characteristics. His heavenly retinue practiced the true Dharma of monks and attained arhatship, all being of sharp faculties; among the heavenly women, some attained the stage of srotāpanna, sakṛdāgāmin, or anāgāmin, never to return here, entering parinirvāṇa right there. This is what is meant by a Brahmā king not relinquishing the body or receiving a body, but attaining the Buddha path in his present body."
