【二相──悉达太子二相】
﹝出佛本行集经﹞
梵语悉达,华言顿吉,即佛幼时之名也。二相者,谓佛初生时,净饭王令相师占之。相师云:太子相好,具有轮王及成佛之相也。
[一、轮王相],轮王相者,谓转轮圣王,亦具三十二相也。相师言:太子具足是相,若其在家,当作转轮圣王,王四天下也。(三十二相者,足安平相、千辐轮相、手指纤长相、手足柔软相、手足缦网相、足跟满足相、足趺高妙相、腨如鹿王相、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。四天下,即四洲,东弗于逮、南阎浮提、西瞿耶尼、北郁单越也。)
[二、成佛相],成佛相者,佛具三十二相。相师言:太子具足是相,若舍王位,出家求道,必得成佛,名遍十方,化导一切也。
