Yogācārabhūmi-śāstra: Volume Thirty-Four (80 Volumes)

The cultivation of śamatha (calm abiding) refers to causing the mind to abide peacefully through the nine methods, as previously explained. The cultivation of vipaśyanā (insight) is also as explained before.

The cultivation of the mundane path refers to perceiving the coarse aspects of the lower realms (such as the desire realm) and perceiving the tranquil aspects of the higher realms (the form realm and formless realm), thereby attaining up to the Sphere of Nothingness, renouncing attachment to all levels of existence within the mundane sphere.

The cultivation of the supramundane path refers to the right contemplation that suffering is truly suffering, the origin is truly the origin, cessation is truly cessation, and the path is truly the path. Through the supramundane Noble Path endowed with right view and other factors, free from defilements, one attains up to the Sphere of Neither Perception nor Non-Perception, renouncing attachment to all levels of existence via the supramundane path.
