Capacity is all-accommodating. All that we can know is known through some capacity - higher things through a higher capacity and ordinary things through an ordinary capacity. Even when we hear a voice it is through a capacity. A house is a capacity which helps us to hear it more clearly; the ears are a capacity in which it becomes audible; the mouth is a capacity in which the word is formed; the mind is a capacity in which we perceive it. The nature of every capacity is different, but the whole phenomenon is that of capacity.
