2.205

又如殖種於空終不得生。糞壤之地乃能滋茂。如是入無為正位者不生佛法。起於我見如須彌山。猶能發于阿耨多羅三藐三菩提心生佛法矣　此二喻。我見之地生滋茂惠芽。二乘斷滅諸見如空中種也。

"Furthermore, it is like planting seeds in the open sky: they can never grow; only in land with dung and soil can they flourish. In this way, those who enter the correct position of the unconditioned do not produce the Buddha Dharma. Yet even if one gives rise to views of self as high as Mount Sumeru, one is still able to generate the aspiration for anuttarā-samyak-saṃbodhi and produce the Buddha Dharma." This is the second parable: the soil of self-views gives birth to flourishing sprouts of wisdom; the two vehicles' severing all views is like planting seeds in the open sky.
