3.171

問：須彌大海入毛芥中，巨細相違，如何能入？答曰：西方諸師略作三解。一云：一切諸法以如為體，所依真如離諸相故，能依諸法無定大小，故得相容。二云，依唯識理，一切諸法皆不離識，隨心變現無有定相，故得相容。三云：一切諸法從因緣生，因緣如幻，幻無定相，故得容也。

Question: Mount Sumeru and the great ocean entering into a hair-pore or a mustard seed: large and small are in conflict; how can they enter? Answer: The masters of the western region briefly offer three explanations. The first says: All phenomena take suchness as their substance. Because the true suchness upon which they depend is free from all marks, the phenomena that depend on it have no determinate size; therefore, they can accommodate one another. The second says: According to the principle of consciousness-only, all phenomena are not apart from consciousness; manifesting according to the mind, they have no determinate marks; therefore, they can accommodate one another. The third says: All phenomena arise from causes and conditions; causes and conditions are like illusions; illusions have no determinate marks; therefore, they can accommodate one another.
