妙法蓮華經玄贊 3.29

3.29

四無礙解以三門分別：一列名，二辨相，三出體。列名者：一法無礙解，二義無礙解，三詞無礙解，四辨才無礙解。辨相者，法謂能詮名句文教，義謂所詮真俗諦理，詞謂諸方音聲，辨才謂七種辨才。緣此四智無所拘礙，名無礙解。有多差別，如〈決擇〉、〈菩薩地〉及《十地論》說。出體者，此四即以無漏後得智為體，非證真故；義無礙解亦通正智，初地分得，九地任運離障圓成，佛果滿足。

The four unhindered understandings are differentiated through three categories: first, listing their names; second, distinguishing their characteristics; third, identifying their intrinsic nature. Listing their names: first, the unhindered understanding of dharmas; second, the unhindered understanding of meanings; third, the unhindered understanding of expressions; fourth, the unhindered understanding of eloquence. Distinguishing their characteristics: "dharmas" refers to the expressing names, phrases, letters, and teachings; "meanings" refers to the expressed ultimate and conventional principles of truth; "expressions" refers to the sounds and speeches of various regions; "eloquence" refers to the seven kinds of eloquence. Cognitions that take these four as objects without obstruction or impediment are called unhindered understandings. There are many distinctions, as explained in the "Viniścaya-saṃgrahaṇī," the "Bodhisattvabhūmi," and the Daśabhūmika-śāstra. Identifying their intrinsic nature: these four take untainted subsequent cognition as their substance, because they do not [directly] realize truth; the unhindered understanding of meanings also extends to correct cognition. They are partially attained at the first bhūmi, effortlessly purified of obstacles and fully brought to perfection at the ninth bhūmi, and completely fulfilled at the buddha-fruition.
