He spent much time wondering just how big Big is. After years of contemplation on this topic he concluded Big is too big for him to think meaningfully about anymore. So instead he asked himself how small is Small. He reasoned that like temperature there has to be some kind of lower limit to how small something can get, even if there is no upper limit on Big. He looked deeper and deeper into the meaning of small and realized he had no idea about that either. He spent a good deal of time reading what the masters had written on Big and Small. Then he realized, they had no idea either.

If one cannot comprehend either the very Big or the very Small, then what can one comprehend, except that which is hopelessly sundry, hopelessly commonplace and mundane. Such as life. Or death. Or happiness and sorrow. Or even loneliness. Does happiness have a structure? Or sorrow for that matter.
