仁王護國般若波羅蜜多經 1.55

1.55

「善男子！有情之受，依世俗立，若有若無。但生有情妄想憶念，作業受果皆名世諦。三界六趣一切有情，婆羅門、剎帝利、毘舍、首陀，我人知見，色法心法如夢所見。

"Good son! The experiences of sentient beings are established based on the conventional, whether as existent or non-existent. Only that which gives rise to sentient beings' false conceptualizations and recollections, creating karma and experiencing retribution, is called conventional truth. All sentient beings of the three realms and six destinies—brāhmaṇas, kṣatriyas, vaiśyas, and śūdras, with their views of self and person—their dharmas of form and dharmas of mind are like what is seen in a dream.
