金師子章雲間類解 1.78

1.78

始自形骸之色、思慮之心，終至佛果一切種智，皆無自性，徹於有表唯是真空。以色性自空，非色滅空也。

Beginning with the form of the physical body and the thoughts of the mind, and ending with the all-aspect wisdom (sarvākārajñatā) of the fruit of buddhahood, all lack intrinsic nature, and penetrating beyond existence they are purely true emptiness. Because the nature of form is of itself empty, not that form ceases and becomes empty.
