大般涅槃經集解 52.18

52.18

案僧亮曰：四等成就，得入大乘也。寶亮曰：第七聚也。實謂大乘無相之解，菩薩知取相為過，捨相是道，理歸一實，更無異塗也。

Sengliang states: When the four equanimities are accomplished, one is able to enter the Mahāyāna. Baoliang states: This is the seventh group. 'Reality' refers to the Mahāyāna's signless understanding; the bodhisattva knows that grasping at marks is a fault and abandoning marks is the Path; the principle reverts to the one reality, and there is no other path.
