注大乘入楞伽經 3.200

3.200

言外道於三無為無作法，而建立有性。佛言此離性非性，類明一切諸法離於有無，猶如毛輪垂髮由翳目而生，兔馬等角本自無有。

This means that non-Buddhists superimpose an existent intrinsic nature onto the three unconditioned and uncompounded phenomena. The Buddha says that these are free from intrinsic nature and non-intrinsic nature; analogously explaining that all phenomena are free from existence and non-existence, just as a tuft of hair or hanging strands of hair are produced by cataracts of the eye, and the horns of hares, horses, and the like are originally non-existent.
