12.123

三藏云：西方兩釋。一云，八地已上方入滅定，七地已下頓悟菩薩即不能入，所以者何，七地已來超三界惑而現在前故不能入，今云六七地中能入滅定者，據正體智相應定數緣寂滅故名滅盡定。非二十四不相應中，滅盡定。一云，初地已上皆入滅定，故楞伽云：佛告大慧，從初地乃至六地入滅盡定，聲聞緣覺亦入滅定，乃至聲聞緣覺即不得入，七地菩薩念念入滅定，今云第六地所入者，以第六地中分得無相故能伏煩惱，能伏煩惱能破入滅定障。

The Tripiṭaka Master says: There are two explanations in the West. One says that only from the eighth stage onwards does one enter the attainment of cessation; below the seventh stage, bodhisattvas of sudden awakening are unable to enter it. Why is this? Up through the seventh stage, afflictions transcending the three realms still manifest before them, and therefore they cannot enter it. When it says here that one can enter the attainment of cessation in the sixth and seventh stages, this refers to the mental factor of concentration associated with the fundamental wisdom, which takes cessation as its object and is therefore called the attainment of cessation; it is not the attainment of cessation among the twenty-four non-concurrent [formations]. Another [explanation] says that from the first stage onwards all enter the attainment of cessation. Thus the Laṅkāvatāra Sūtra states: 'The Buddha told Mahāmati: From the first stage up to the sixth stage, they enter the attainment of cessation; śrāvakas and pratyekabuddhas also enter the attainment of cessation, up to where śrāvakas and pratyekabuddhas cannot enter; the bodhisattva of the seventh stage enters the attainment of cessation in every thought-moment.' When it mentions here that which was entered in the sixth stage, it is because in the sixth stage one partially attains signlessness and is therefore able to subdue afflictions; being able to subdue afflictions, one can break through the obstacle to entering the attainment of cessation.
