華嚴經義海百門 1.107

1.107

三、明三性者，謂塵上迷心所執，計有相生，以為實也。今了塵圓小之相取不可得，惑相自亡，是為遍計相無性，為人無我也。又塵與自心為緣，心法方起。今了緣無自體，依心方現，無自體生，是為依他也，無生性是法無我也。由二義現前，乃圓成勝義性也。

Third, "clarifying the three natures": what is grasped by the deluded mind on the dust mote, contriving that existing characteristics arise and taking them to be real: now realizing that the round and small characteristics of the dust mote cannot be apprehended, the deluded characteristics naturally perish; this is the parikalpita nature being without characteristic-nature, which is the selflessness of persons. Furthermore, the dust mote serves as a condition for one's own mind, and mental phenomena only then arise. Now realizing that conditions have no self-essence and only appear in dependence on the mind, having no production of their own self-essence, is the paratantra [nature]; its unborn nature is the selflessness of dharmas. Because these two meanings are manifest before one, it is the pariniṣpanna ultimate nature.
