瑜伽論記 1.631

1.631

又解：是觸；六、虛空；七、擇滅；八；非擇滅；九、真如；十、苦樂離繫義謂不動滅，非受離繫義謂想滅，及受離繫義謂受滅，此不動、想受滅、無為，合為第十。

Another explanation says: it is contact. Sixth, space; seventh, analytical cessation; eighth, non-analytical cessation; ninth, tathatā; tenth, the meaning of detachment from suffering and pleasure refers to unshakeable cessation, the meaning of detachment from non-feeling refers to cessation of perception, and the meaning of detachment from feeling refers to cessation of feeling; these—the unshakeable and the cessation of perception and feeling unconditioned factors—are combined to form the tenth.
