Pillar of salt. Perhaps there is some meaning to it. Why of all things, a pillar of salt? To me, what comes to mind is a statue. The same way that we carve statues of people, although we don't use salt blocks to do it (I don't think). Perhaps in their time salt blocks were used for statuary.
The person who looks back always never lives now. He is frozen in time. He is a living monument to his own past. But one thing is for sure, he is not present. He has ceased to be living now. He lives yesterday.

The Hebrew for pillar is natsiyb, which refers to...something set to watch over something else. -

We must not stand as a watchman over yesterday. We must not become a living monument to what has passed. Life is now. Yesterday exists only as a thought in your mind NOW.
Religions got caught in worshiping the past. When that sacred moment that we worship took place then it took place NOW.
