17.324

一切異生能行故，唯除已入遠地菩薩者，向下文說，六地入滅定，七地菩薩念念入滅盡定，道理初地以上皆得滅定，以得地相初二三地相同世間，四地預流五地一來，故前五地未得滅定，六地當不還，七地當阿羅漢，故論偏說得滅盡定。

As for "because all ordinary beings are able to practice it, with the sole exception of bodhisattvas who have already entered the far-reaching ground": the text below says that on the sixth ground one enters the concentration of cessation, and a bodhisattva on the seventh ground enters the concentration of cessation thought-moment by thought-moment. In principle, from the first ground upward, all attain the concentration of cessation. Yet, because the characteristics of the grounds attained on the first, second, and third grounds are similar to the worldly, the fourth ground corresponds to the stream-enterer, and the fifth ground to the once-returner, on the first five grounds one has not yet attained the concentration of cessation. The sixth ground corresponds to the non-returner, and the seventh ground corresponds to the arhat; therefore, the treatise speaks specifically of attaining the concentration of cessation [there].
