說無垢稱經疏 6.644

6.644

贊曰：此明經用。有三十句，舊有二十五句。此中四句。一佛印所印。無相真如，名為佛印。餘證真如，猶未圓故，獨名佛印。教為理所印，故言佛印所印。舊云「陀羅尼印」，總持性印所印，亦即真如無相理印。二能分別能開示四不退輪。三六到彼岸由斯而起。四善攝所攝，所應攝受者，謂教所詮善妙道理，及教所益一切有情。舊云「善分別義」，即此二種。

Commentary: This clarifies the function of the sūtra. It has thirty phrases; the older version had twenty-five phrases. Here are four phrases: 1. Sealed by the Buddha's seal: signless tathatā is called the Buddha's seal; other realizations of tathatā are not yet complete, so it is uniquely called the Buddha's seal. Because the teaching is sealed by the principle, it is called "sealed by the Buddha's seal." The older version says "dhāraṇī seal," sealed by the seal of the nature of total retention, which is also the seal of the principle of signless tathatā. 2. Able to distinguish and reveal the four irreversible wheels. 3. The six perfections arise from this. 4. Excellently embraced by what it embraces; "that which should be embraced" refers to the excellent and marvelous principles explained by the teaching, and all sentient beings benefited by the teaching. The older version says "excellently distinguishing the meaning," which is precisely these two kinds.
