維摩經玄疏 2.161

2.161

十、順道法愛不生者，觀生死即涅槃，生一切諸禪定、三昧等功德；觀煩惱即菩提，生諸陀羅尼門、四無所畏、十八不共法、四無閡智、一切種智，於順道法，不愛、不著，是為觀行乘。

Tenth, not giving rise to attachment to dharmas conforming to the path: contemplating saṃsāra as identical to nirvāṇa gives rise to the merits of all dhyānas, samādhis, and the like; contemplating defilements as identical to bodhi gives rise to the gates of dhāraṇī, the four fearlessnesses, the eighteen unshared dharmas, the four unobstructed knowledges, and the knowledge of all aspects. Toward dharmas conforming to the path, having neither attachment nor clinging: this is the vehicle of contemplative practice.
