【七阶──藏教七阶】
  ﹝出天台四教仪集注﹞
  藏教者,即小乘经律论三藏教也。阶者,阶级次第也。谓藏教菩萨修行之次第也。(菩萨,梵语具云菩提萨埵,华言觉有情。)
  [一、四弘誓愿],弘者,大也。誓者,要制其心也。愿者,志求满足也。谓菩萨从初发心,观四谛境,发四弘誓,一、未度者令度,即众生无边誓愿度,此观苦谛境。二、未解者令解,即烦恼无数誓愿断,此观集谛境。三、未安者令安,即法门无量誓愿学,此观道谛境。四、未得涅槃者令得涅槃,即佛道无上誓愿成,此观灭谛境也。(梵语涅槃,华言灭度。)
  [二、三祇修六度],三祇者,三阿僧祇劫也。六度者,布施、持戒、忍辱、精进、禅定、智慧也。度,越也,越生死流,到涅槃岸也。谓菩萨既发心已,必须行六度行,填满本愿,是为三祇修六度。(梵语阿僧祇劫,华言无数时。)
  [三、百劫种相好],劫,梵语具云劫波,华言分别时节。百劫种相好者,一增一减为一小劫;凡历二十番增减,为一中劫;八十番增减,为一大劫。谓菩萨于百劫中,种诸相好。用百福德成一相好,如是至三十二相具足,而身清净也。(人寿从十岁增至八万四千岁,名增劫。从八万四千岁减至十岁,名减劫。如是一增一减,名一小劫。三十二相者,足下安平相,千辐轮相,手指纤长相,手足柔软相,手足缦网相,足跟满足相,足趺高好相,端如鹿王相,手过膝相,马阴藏相,身纵广相,毛孔生青色相,身毛上靡相,身金色相,身光面各一丈相,皮肤细滑相,七处平满相,两腋满相,身如师子相,身端直相,肩圆满相,四十齿相,齿白齐密相,四牙白净相,颊车如师子相,咽中津液得上味相,广长舌相,梵音深远相,眼色如金精相,眼睫如牛王相,眉间白毫相,顶肉髻成相也。)
  [四、六度相满],六度相满者,谓菩萨修行六度之相圆满也。如尸毗王代鸽,即檀度满也。普明王舍国,即戒度满也。羼提仙人被歌利王割截身体,慈忍不动,血变为乳,即忍度满也。大施太子抒海,即精进度满也。尚阇黎鹊巢顶上,即禅度满也。劬嫔大臣分阎浮提为七分,城邑山川均等,故能息诤,即智度满也。如上六人,皆释迦往昔所修之行,是为六度相满。(梵语尸毗,华言与。代鸽者,遍割身肉与鹰以代鸽命,身肉俱尽,不恼不死,自誓真实,感身平复也。梵语羼提,华言忍辱。梵语歌利,华言恶世无道。大施太子求如意珠济贫,得珠堕海,抒海取之,言欲酌海干而取之也。筋骨断坏,终不解废,诸天见而问之,答曰:吾生生不休。诸天愍之,助其抒海,海水减半,龙恐海干,令夜叉送珠还之。尚阇黎者,螺髻仙人,名此人得四禅定,出入息断,鸟谓为木,于髻生卵。定起欲行,恐鸟母不来,即更入定,待鸟飞去,方始出定。梵语阎浮提,华言胜金洲。梵语释迦,华言能仁。)
  [五、兜率降生],梵语兜率,华言知足。降生者,谓菩萨将补佛处,出世度生,即从兜率天降生人间,以补其处,是为兜率降生。(菩萨即释迦佛也。补佛处者,前佛既灭,而此菩萨即补其处也。)
  [六、降神出家],谓菩萨既降神出胎,厌生老病死之苦,而欲脱离,故求出家,入山修道,是为降神出家。
  [七、菩提树下成道],梵语菩提,华言道。谓菩萨自知成道时至,于菩提树下,破诸魔众。魔王败绩,鬼兵退散,菩萨安坐不动,即成佛道,是为菩提树下成道。(菩提树者,谓佛于此树下成道,故名菩提树也。)
