佛頂尊勝陀羅尼經教跡義記 1.81

1.81

述曰：第四其知所受，帝釋即見善住天子當受七返之身，所謂猪、狗、野干、獼猴、蟒蛇、鳥、鷲等身，食諸穢惡不淨之物。言猪身者，《大智度論》云：「由邪憍慢故，故受猪身。」《提謂經》云：「由癡虛受信施四事供養故，故受猪身。」又《法華經》曰：「由謗斯經故，故受猪、狗、野干等身。」又云：「由飲酒造癡業故，受猪身。」《提謂經》云：「惡口慳貪故，故受猪身。」為物慳貪。言野干身者，《大智度論》云：「由輕慢善人故，受野干身。」又《提謂經》云：「由奸猾語故，受野犴身。」郭朴云：「野犴，形大於狐，又能緣樹。」言獼猴身者，《大智論》云：「由輕躁短促故，受獼猴身。」《提謂經》云：「由遊戲放逸故，受獼猴身。」又蟒蛇身者，亦《大智度論》云：「由瞋恚多故，故受毒蛇等身。」《爾雅》云：「蟒，王蛇。」郭朴云：「蛇之大故，故名為王。」問曰：「由何此等畜生身有毛羽？」答曰：「《大智度論》云：『由受觸樂故，身生毛羽。』」良為善住先造是業故，故受斯苦報也。

The commentary says: Fourth, fully knowing what is to be received. Śakra then saw that the devaputra Susthita would receive seven rebirths, namely the bodies of a pig, a dog, a jackal, a monkey, a python, a crow, a vulture, and the like, eating all sorts of foul, repulsive, and impure things. Regarding the pig's body, the Dàzhìdù lùn says: "Because of deviant pride, one receives the body of a pig." The Tiwei jing says: "Because of receiving the four requisites of offerings from donors in delusion and in vain, one receives the body of a pig." Furthermore, the Lotus Sūtra says: "Because of slandering this sūtra, one receives the bodies of pigs, dogs, jackals, and the like." It also says: "Because of drinking alcohol and creating deluded karma, one receives the body of a pig." The Tiwei jing says: "Because of harsh speech and stinginess, one receives the body of a pig," being stingy with material things. Regarding the jackal's body, the Dàzhìdù lùn says: "Because of slighting and looking down upon good people, one receives the body of a jackal." Also, the Tiwei jing says: "Because of treacherous and deceitful speech, one receives the body of a jackal." Guo Pu says: "The yegan is larger than a fox and can climb trees." Regarding the monkey's body, the Dàzhìdù lùn says: "Because of being frivolous and impatient, one receives the body of a monkey." The Tiwei jing says: "Because of frivolous play and heedlessness, one receives the body of a monkey." Furthermore, regarding the python's body, the Dàzhìdù lùn also says: "Because of having much anger, one receives the body of a venomous snake and the like." The Erya says: "The mang is the king snake." Guo Pu says: "Because the snake is large, it is called a king." Question: "Why do these animal bodies have hair and feathers?" Answer: "The Dàzhìdù lùn says: 'Because of attachment to the pleasure of touch, hair and feathers grow on the body.' Truly, it is because Susthita previously created such karma that he receives this painful retribution."
