俱舍論疏 20.191

20.191

論「和合有情故名為軛」，總釋軛名。令有情與界、趣、生共和合故名軛，猶如車軛。《正理論》云「於界、趣、生和合名軛。」

The Śāstra says: "Because they yoke sentient beings, they are called yokes (yoga)"—this generally explains the name yoke. Because they yoke sentient beings together with realms, destinies, and births, they are called yokes, just like a cart's yoke. The Nyāyānusāra states: "Yoking to realms, destinies, and births is called a yoke."
