2.177

行色無色界道不以為勝　二善趣也。無想非想外道計著以為涅槃第一最勝。菩薩和光知其卑陋。肇曰。上二界道受有之因雖同其行知其卑陋。

"He walks the paths of the form and formless realms yet does not consider them superior." Second, the good destinies. The non-conceptual and non-non-conceptual states are grasped by tīrthikas as nirvāṇa, the foremost and most supreme. The bodhisattva blends his light, knowing they are base. Zhao says: "The paths of the upper two realms are the causes for receiving existence; although he conforms to their practice, he knows they are base."
