Did this cause that or was that caused by this? Or was this caused by that or that the cause of this? The exact causes of things are difficult to apprehend. That’s because things usually don’t have just one cause. And yet the mind in looking for explanations always seeks the cause of things.
Causes always exist in time. In fact, one can say perhaps that they actually constitute the fabric of time itself. But even if one could uproot every cause of every cause one would still not arrive at the fundamental cause of causes. Why is this? Because the cause of causes is not itself to be found in causes.
