五、識處背捨。若捨虛空，一心緣識入定時，即觀此定依陰、入、界，故有無常、苦、空、無我，虛誑不實，心生厭背而不受著，深入一向不迴，是為五識處背捨。

Fifth, the liberation of the sphere of consciousness. If, casting off space, one single-mindedly takes consciousness as object upon entering concentration, one then contemplates that this concentration relies on the skandhas, āyatanas, and dhātus, and therefore is impermanent, suffering, empty, non-self, deceptive, and unreal; generating a mind of revulsion and turning away, one does not cling to or attach to it, but enters deeply and single-mindedly without turning back—this is the fifth, the liberation of the sphere of consciousness.
