大方廣佛華嚴經隨疏演義鈔 25.29

25.29

疏「平等與藏通此二義」者，藏通真如，是不空如來藏。藏通虛空，是空如來藏。平等通二者，一真如體性平等、二虛空無相平等。此二不二，是真平等，悟法性空是真如故。經云「汝已嚴淨此法身」者，對上真如，即是法身出障名淨。「因華行滿」是已莊嚴，易故不釋。

On the commentary's "Equality and womb/storehouse extend to both of these meanings": "womb/storehouse" extends to tathatā, which is the non-empty tathāgatagarbha; "womb/storehouse" extends to empty space, which is the empty tathāgatagarbha. "Equality" extends to both: first, the essence and nature of tathatā are equal; second, the signlessness of empty space is equal. These two being non-dual is true equality, because awakening to the emptiness of dharmatā is precisely tathatā. When the sūtra says "You have already purified and adorned this dharmakāya": in relation to the tathatā above, it is precisely that the dharmakāya emerging from obscuration is called pure. "The flower of cause and practices being fulfilled" is "already adorned"; because it is simple, it is not explained.
