問：「言比量者，為比量智？為所觀因？」答：「即所觀因，及知此聲所作因智，此未能生比量智果。知有所作處，即與無常宗不相離，能生此者，念因力故。」

Question: 'When one says "inference" (anumāna-pramāṇa), is it the inferential cognition, or the observed reason?' Answer: 'It is the observed reason and the cognition knowing that this sound has the reason of being produced; this is not yet able to produce the result of inferential cognition. Knowing that where there is being produced, it is inseparable from the thesis of impermanence—what is able to produce this is due to the power of remembering the reason.'
