涅槃經遊意 1.62

1.62

如聞佛性者名第一義空，便種種解釋，或云從境為名，或云即於真諦。彼云：佛性是智，第一義空是境，但智即境，故云佛性名第一義空。又云：佛性是俗諦，但俗即真故，云佛性名第一義空也。今明此語未足。佛性者名第一義空，智者見空及以不空，此始成一句耳，是故發初與他異。

For instance, hearing that Buddha-nature is named the emptiness of the ultimate truth, they offer various explanations: some say it is named after the cognitive object, while others say it is precisely the ultimate truth. They say: Buddha-nature is wisdom, and the emptiness of the ultimate truth is the cognitive object, but since wisdom is precisely the cognitive object, it is said that Buddha-nature is named the emptiness of the ultimate truth. Furthermore, they say: Buddha-nature is conventional truth, but since conventional is precisely ultimate, it is said that Buddha-nature is named the emptiness of the ultimate truth. Now we clarify that these statements are insufficient. Buddha-nature is named the emptiness of the ultimate truth; the wise see emptiness as well as non-emptiness—only this forms a complete proposition. Therefore, from the very outset, our position differs from that of others.
