Yogācārabhūmi Śāstra, Volume 34 (80)

Original text:奢摩他修者。谓九种行令心安住。如前已说。毗钵舍那修亦如前说。世间道修者。谓于诸下地见粗相故。于诸上地见静相故。乃至能趣无所有处。一切离欲。出世道修者。谓正思惟。苦真是苦。集真是集。灭真是灭。道真是道。由正见等无漏圣道。乃至能趣非想非非想处。一切离欲。

Explanation: The cultivation of śamatha means using nine methods to settle the mind in stability, just as was said before. The cultivation of vipaśyanā is also as said before. The meaning of cultivation by the worldly path is that one sees the coarse marks in the lower realms (the desire realm) and sees the tranquil marks in the higher realms (the form realm and the formless realm), and can even proceed up to the sphere of nothingness, being free from desire and not attached to desire at all levels, unimpeded in the worldly. The meaning of cultivation by the supramundane path is being able to correctly contemplate that the truth of suffering is truly suffering, the truth of origination is truly origination, the truth of cessation is truly cessation, and the truth of the path is truly the path. Because of the noble, untainted path consisting of right view and so forth, one can even proceed up to the sphere of neither perception nor non-perception, being free from desire and not attached to desire at all levels, unimpeded on the supramundane path.
