前中，景師釋云：諸聖弟子乃至證入無動無所有非想處定者，四禪及下二空，并名無動定，斷欲界欲九無礙八解脫名趣初禪，離外散動欲等無動定行，離初禪九無礙八解脫，名趣二禪。離尋伺動無動之行，離二禪九無礙道八解脫道，名趣三禪。離喜所動無動之行，離三禪欲九無礙八解脫，名趣四禪。離樂所動無動之行，離四禪欲九無礙八解脫，名趣空處。雜色想有對想種種別異想動無動之行，離空處欲九無礙八解脫時，名趣識處。離彼空處外緣門動無動之行，以空處空外取空相，名外門動，識處內緣於識，名為無動。離於識處九無礙八解脫時，名趣無所有行。離於欲界四禪空處，名取第九解脫并名證無動定。離於識處第九解脫，名證入無所有定。離無所有第九解脫，名證入非非想定。

In the former part, Master Jing explains: regarding 'All noble disciples up to entering the concentrations of the Immovable, Nothingness, and Neither Perception nor Non-perception,' the four dhyānas and the lower two formless realms are together called immovable concentration. Abandoning the desires of the desire realm through nine unobstructed paths and eight liberations is called proceeding to the first dhyāna. Practices of immovable concentration that are free from the movement of external distraction, desire, and so forth, through abandoning the first dhyāna by nine unobstructed paths and eight liberations, are called proceeding to the second dhyāna. Practices of immovable concentration free from the movement of investigation and reflection, through abandoning the second dhyāna by nine unobstructed paths and eight liberation paths, are called proceeding to the third dhyāna. Practices of immovable concentration free from that moved by joy, through abandoning the desires of the third dhyāna by nine unobstructed paths and eight liberations, are called proceeding to the fourth dhyāna. Practices of immovable concentration free from that moved by pleasure, through abandoning the desires of the fourth dhyāna by nine unobstructed paths and eight liberations, are called proceeding to the stage of boundless space. Practices of immovable concentration [free from] the movement of notions of gross form, notions of sensory contact, and notions of manifold diversity, when abandoning the desires of the stage of boundless space by nine unobstructed paths and eight liberations, are called proceeding to the stage of boundless consciousness. Practices of immovable concentration free from the movement of that stage of boundless space's external apprehension—since taking the appearance of space outside the space of the stage of space is called movement through an external gate, while the stage of consciousness internally apprehends consciousness, it is called immovable. When abandoning the stage of consciousness through nine unobstructed paths and eight liberations, it is called the practice of proceeding to nothingness. Abandoning the desire realm, the four dhyānas, and the stage of boundless space is called attaining the ninth liberation and is also called realizing immovable concentration. Abandoning the stage of consciousness through the ninth liberation is called realizing and entering the concentration of nothingness. Abandoning nothingness through the ninth liberation is called realizing and entering the concentration of neither perception nor non-perception.
