tad abhavat samyogabhavohanam tad drseh kaivalyam

If that blindness is absent, union is absent and ceases. This is the liberation of the Seer.

Yoga Sutras of Patanjali, 2.25

tad = that (blindness to absolute truth, ignorance)
abhavat = absence
samyoga = union
abhavo = absence
hanam = cessation
drseh = of the Seer
