瑜伽論記 2.168

2.168

有性者，有性謂有體性，果性謂因所有，即體名有，義名果性。此中間為有體作障緣，為果義作障緣。若有體是障緣，體性常有，是則性永不得顯，顯如未顯，常有體故，因亦是有，何不為障而獨果有能為障耶？

'Existence-nature': existence-nature means possessing substantial entity; effect-nature means that which is possessed by the cause. The entity is called existence; the meaning is called effect-nature. Between these, do they act as an obstructing condition for the substantial entity, or do they act as an obstructing condition for the meaning of the effect? If possessing an entity is the obstructing condition, the substantial entity is permanently existent; if so, the nature could never be manifested, and manifestation would be like non-manifestation, because it permanently has an entity. The cause is also existent; why does it not act as an obstruction, while the effect alone, being existent, can act as an obstruction?
