大乘入道次第開決 1.17

1.17

三業清潔悟二等者。三業清潔故名為童。謂如童子身語意行皆無咎故。悟二世間故亦為真。了眾生器悉皆虛假。心無礙故。

'The three karmas are pure and undefiled, awakening to the two…', and so forth: because the three karmas are pure and undefiled, it is called 'youthful' (kumārabhūta). That is, just like a youth, actions of body, speech, and mind are all without fault. Because of awakening to the two worlds, it is also 'true'. One completely understands that the sentient world and the receptacle world are all provisional and false, because the mind is without obstruction.
