「如是二定至作意為先」者，作意不同，對簡差別。前無想定，為求無想異熟解脫厭壞於想，以出離心想作意為先，即無想定能出離生死。又解：能出離想也。此滅盡定為求寂靜而住，厭壞散動，以止息心想作意為先。止息即止息心、心所法。又解：止息想雖亦止息受等，以想近強，故別標也。

"These two attainments [...] preceded by mental orientation": their mental orientations differ, distinguishing their difference by contrast. The preceding attainment devoid of ideation seeks liberation as the maturation of non-ideation (asaṃjñi-vipāka) and detests ideation, being preceded by the mental orientation toward the idea of renunciation (niḥsaraṇa); that is, the attainment devoid of ideation can lead out of saṃsāra. Another explanation: it can lead out of ideation. This attainment of cessation seeks to abide in tranquility and detests distraction and agitation, being preceded by the mental orientation toward the idea of pacification (praśama). Pacification means the pacification of mental and mental-factor dharmas. Another explanation: although it also pacifies feeling and the rest, ideation is proximate and forceful; hence, it is specifically indicated.
