3.27

「一光下照諸阿修羅、諸夜叉等、諸乾闥婆、諸迦樓羅、諸緊那羅、諸摩睺羅伽、諸龍、諸羅剎、諸富單那、諸金毘羅、諸噉人精氣鬼、諸鳩槃茶、諸吉遮、諸曠野鬼、諸餓鬼、諸食吐鬼、諸食涕唾鬼、諸食膿血鬼、諸食屎尿鬼、諸山神、諸樹神、諸水神。如是等若干百千諸鬼神等，其身暫時作天身色柔軟悅樂，譬如比丘入第三禪，是諸鬼等各隨業行，自發三種菩提之心。諸餓鬼等，舌相光現時，猶如冷水滅節間火，火既滅已，融銅墮地直陷入地。時諸餓鬼皆悉張口唱言：『飢飢，於千萬歲不曾見水，今遇此水除熱清涼，是誰力耶？』空中聲曰：『愚癡餓鬼，有佛世尊放舌光明，其光照汝，令汝苦毒悉得休息。』作是語已，一一鬼前見一慈母坐蓮華臺，譬如慈母抱持嬰兒與乳令飲，使鬼飽滿；既飽滿已，發菩提心；既發心已，一一慈母化成一佛。時一一佛亦放舌相救諸餓鬼。」

“One ray shines downward upon the asuras, yakṣas, gandharvas, garuḍas, kinnaras, mahoragas, nāgas, rākṣasas, pūtanas, kumbhīras, spirits who consume human vitality, kumbhāṇḍas, kṛtyas, spirits of the wilderness, pretas, vomit-eating pretas, spittle-eating pretas, pus-and-blood-eating pretas, feces-and-urine-eating pretas, mountain spirits, tree spirits, and water spirits. The bodies of several hundred thousand such spirits and deities temporarily take on the color of devas' bodies, becoming supple, joyful, and serene, like a monk entering the third dhyāna. In accordance with their respective karmic practices, these spirits spontaneously arouse the three kinds of bodhicitta. When the light of the mark of the tongue appears to the pretas, it is like cold water extinguishing the fire between their joints. Once the fire is extinguished, the molten copper falls to the ground and sinks straight into the earth. At that time, all the pretas open their mouths and cry out: ‘We are starving, starving! For tens of millions of years we have never seen water. Now we encounter this water, which dispels the heat with cool refreshment. Whose power is this?’ A voice in the sky proclaims: ‘Foolish pretas, there is a Buddha, a Bhagavat, who emits light from his tongue. His light shines upon you, causing all your bitter afflictions to come to rest.’ When these words have been spoken, before each preta appears a compassionate mother seated on a lotus throne. Just as a compassionate mother embraces an infant and gives it milk to drink, she satisfies the pretas. Once satisfied, they arouse the bodhicitta. Once they have aroused this aspiration, each compassionate mother transforms into a Buddha. At that time, each Buddha also emits the mark of the tongue to deliver the pretas.”
