Our souls are permanent.
This world is temporary.
We are constantly bombarded with the temporary while our souls are in this world.
How does the soul get the permanence it relates to if not from reminders about that which is Permanent?
After time without reminders its as if the soul mistakes itself to be temporary like the world.
This is how souls get lost.
Every soul needs reminding about its permanence and about the Permanent, Himself who can give it what it needs: permanence.
