楞伽阿跋多羅寶經註解 3.186

3.186

From this section downward, events are cited to demonstrate the harm. 'Śakra Devendra' is an alternate name for the King of the Gods. 'Took the form of a dragon' means he transformed himself into the body of a dragon. 'Pledge' (要) means an agreement. The *Ru Lengqie* says: "He made this pact, saying: 'Kauśika! I shall debate with you. If you are not my equal, your thousand-spoked wheel shall be destroyed. If I am not your equal, let each of my heads be cut off to make amends for having yielded.'" 'Used Śakra's own methods' means he posed objections using the very doctrinal methods composed by Śakra himself. 'Fell into defeat' means failing to win, referring to Śakra's defeat. 'Even animals' refers to things such as this being transformed into the body of a dragon. Furthermore, when it says that worldly treatises must be stayed far away from, it means that since those treatises cause harm like this, how could one not be cautious?
