大乘入道次第開決 1.26

1.26

四無礙諸陀羅尼門等者。此四無礙諸陀羅尼門既以念慧而為體性。是故即名諸善慧法。能除眾生諸煩惱熱。如入池浴而得清涼。是故喻彼清涼池也。然此所行四無礙等。但相似得非真滿得。真在地上。滿第九地。故此但是相似得耳。四無礙等義如下說。此無繁舉。

'The four unhindered [knowledges], the various dhāraṇī-doors', and so forth: since these four unhindered knowledges and various dhāraṇī-doors take mindfulness and wisdom as their essential nature, they are therefore named 'all good and wise dharmas'. They can remove the fever of all afflictions of sentient beings, just like entering a pool to bathe and obtaining cool refreshment; therefore, they are compared to that 'cool pool'. However, these four unhindered knowledges and the like practiced here are only attained in resemblance, not attained in true fullness. True attainment is upon the bhūmis; full attainment is on the ninth bhūmi. Therefore this is only an attainment in resemblance. The meaning of the four unhindered knowledges, and so forth, is explained below; it will not be listed repetitively here.
