淨名經集解關中疏 2.205

2.205

"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.
