楞伽阿跋多羅寶經註解 2.210

2.210

戒取者，非戒為戒也。外道邪習，非因計因，如持雞、狗等戒是也。初果人不取彼戒，謂善見彼受報苦相，徒勞苦行，故不取也。愚夫取者，以五欲等眾具為樂，故求受生。然非三昧之樂，雖求樂果，其實何有？彼初果人不取是為戒，非無自己所持之戒，故曰除迴向自覺勝等，即彼所修戒行迴因向果。戒支者，支謂支分，如七覺支及五支戒等是。雖不取乎彼而取乎此，然非大乘無取之戒，是亦取也。

"Grasping at rules and observances" means taking what is not a precept to be a precept. These are the wrong practices of tīrthikas, who conceive as a cause that which is not a cause, such as keeping the rules of chickens, dogs, and the like. A person of the first fruit does not grasp at those precepts; that is, they see well the characteristics of the suffering of those retributions and the vain toil of their austerities, and therefore do not grasp at them. When foolish common persons grasp at them, they take the requisites such as the five desires to be pleasure, and so seek rebirth. However, these are not the bliss of samādhi. Although they seek a pleasurable fruition, what is there in reality? That person of the first fruit does not take this to be morality; yet it is not that they have no precepts of their own that they uphold. Thus it says: "except in dedicating themselves to the excellence of self-realization..." That is, they dedicate the practice of morality they cultivate from cause toward fruit. Regarding "branches of morality," "branches" means divisions, like the seven factors of awakening and the five branches of morality, and so forth. Although they do not grasp at the former but grasp at the latter, this is still not the non-grasping morality of the Mahāyāna; it is also a form of grasping.
