2.428

謂修學空不以空為證。修學無相無作。不以無相無作為證　修學無起不以無起為證　此下二釋文三。此初明三解脫也。二乘觀三脫樂涅槃故取證。菩薩觀三脫樂大悲故不證　無起者。因緣生法無自性故不生起也。肇曰。此定觀之別門也。

"It means cultivating and learning emptiness without taking emptiness as realization; cultivating and learning signlessness and wishlessness without taking signlessness and wishlessness as realization; cultivating and learning non-arising without taking non-arising as realization." Below, this is the second part, the explanation, which has three sections. This first section clarifies the three liberations. The two vehicles contemplate the three liberations and take delight in nirvāṇa, hence they attain realization. Bodhisattvas contemplate the three liberations and take delight in great compassion, hence they do not realize it. As for 'non-arising': dharmas produced by conditions lack inherent nature, hence they do not arise. Zhao says: "These are distinct approaches to meditative contemplation."
