When the Beis Hamikdash was destroyed, only the Western Wall was left to us, where we were promised, the Divine Presence would never leave and that would never be destroyed.
For all its mystery, consciousness remains the most unique & beautiful of all creation. On Shabbos we let go. We let go of our worries and troubles. We let go of our illusory and grasping sense of control. We let go of what we do and let in who we are. We let go and let G-d.
