One should formulate the inference: The entity of the effect in your school should also be unmanifest, because it is identical to the entity of the cause, like the cause, primordial nature. However, the entity of the effect in their school is exclusively manifest; therefore this objection is made. Alternatively: Your primordial nature should also have its entity manifest, because it is the cause of the effect, like the cause of a subsequent effect; just as in their clinging a sprout, being a cause, must be manifest, hence this objection is established. Alternatively: The effect-nature should not obstruct, because its entity is identical to the cause, like the cause; the cause should also obstruct, because it is identical to the entity of the effect, like the effect. Therefore it is said: 'A single dharma is both cause and effect.'
