大般涅槃經集解 70.81

70.81

案僧亮曰：外道謂法有定性，吉則定吉，不吉則一切不吉也。佛破之云：我無定執，教汝離執也。

Sengliang states: Non-Buddhists hold that dharmas have a fixed nature: if auspicious, they are definitely auspicious; if not auspicious, all are not auspicious. The Buddha refutes him, saying: 'I have no fixed grasp; I teach you to abandon grasping.'
