所未闻经闻之不疑， 不与声闻而相违背。
《维摩诘所说经》卷2
A bodhisattva does not doubt any sutra which hehas never heard before; however, its teachings must not contradict the sound-hearer [sravaka]dharma.

所以，要具有这个闻之不疑的善根，就必须同时不与声闻而相违背，要以这个原则作前提。如果没有这个前提，外道写出来的如是我闻等等，你也信了，那么学佛学到后来，将会变成学外道而不是学佛了。假使不与声闻而相违背，才有可能是真实经典；而般若系列的经典，第三转轮的唯识系列经典，都与二乘声闻解脱道的四部阿含完全没有违背之处，并且更为胜妙。

Therefore, in order to have the wholesome root ofhearing a sutra without any doubt, one should makesure that the sutra’s teachings do not deviate from thesound-hearer dharma. Without this premise, one wouldbelieve in non-Buddhist texts that begin with thewords “Thus have I heard,” and eventually end upstudying non-Buddhism instead of Buddhism. Asutra can only be authentic if it does not contradict thesound-hearer dharma. In fact, the sutras ofprajna series and the sutras of vijnana-only series inthe third round of dharma-transmission donot violate at all the sound-hearer Liberation Way ofTwo Vehicles expounded in the four Agamas, but areeven more wondrous.
