楞伽阿跋多羅寶經註解 2.235

2.235

"Consciousness" refers to the six consciousnesses: the six consciousnesses delight in the dust-realms, treading and traversing in and out of them, hence they are called "tracks." Because deluded consciousness clings to deluded realms, binding karma is thereby formed, and rebirth is received in the six destinies in unbroken continuity. It also says, "the four great elements such as earth," showing that the four great elements cannot produce on their own, but must involve conditions; yet they do not depend solely on conditions, hence it says "are not the conditions of those four great elements." From "Why is this?" downward inquires into and explains this meaning. Nature—the natures of moistening and so forth—and shape are the causes of the form-characteristics of the four great elements; location and the upāya of action are the conditions. If the cause lacks the nature of arising, it will not arise even with conditions; hence it says "the primary elements do not arise." They must form shapes through the combination of various conditions; being "not without shape" means they also depend on conditions. Since they neither exist anywhere nor do not exist anywhere, they fundamentally lack real nature. Arising without nature, the meaning of causes and conditions is then made manifest. As for saying "the vikalpa of tīrthikas": this, along with the earlier phrase "clinging to erroneous truths," both serve to refute error in passing, meaning that the signs of the forms derived from the four great elements are not like the vikalpa and discrimination of tīrthikas; therefore, he says "not mine."
