by that i mean understanding the spiritual analogues or equivalents of many Scriptural passages that might seem to be describing some rather mundane situation. The Bible is a spiritual Book--i'm sure you agree--that describes spiritual principles that there really are no words for, and so an approximation is made by retelling a mundane story where things stand for other things spiritually.
As a rule, these comparisons come to me, at least, after reading/thinking on some ambiguous passage, and praying for clarity, then witnessing some reflection of it in real life--usually with me in the "painful" spot in the situation, if there is one

Thankfully i seem to have got past the more painful lessons--but this also worries me somewhat, as i know one could spend a Methusala's age in learning, and still not grasp the whole of God.
So, these are often things that could not be "proven," like "women watering camels" in Genesis, etc., but still provide meaningful reflections to one who has seen the symbology in those three words (for instance).
