淨名經集解關中疏 2.204

2.204

"For example, lotuses do not grow on high plateaus or dry ground; this flower only grows in low, wet, muddy silt. In this way, those who see the unconditioned and enter the correct position are ultimately unable to produce the Buddha Dharma again. Only amidst the mud of afflictions are there sentient beings who give rise to the Buddha Dharma." This is the second [section], the parables, with two parts in the text: first, the parable that the bodhi lotus exists in the mud of afflictions. The two vehicles' abandoning it to realize the unconditioned is like the high plateau.
