When travelling in Jerusalem today, we see a thriving city. The elderly sit with their staffs in their hands and the children play in the streets, fulfilling the prophecy of Zechariah made 2000 years ago. So why should we mourn on Tisha b Av today? The Zohar teaches us that the inner meaning of Jerusalem is the point of holiness in our heart. On Tisha BAv we need to take stock and mourn that the consciousness of God is so low on our own personal agenda and on that of the world. It is our mourning for the consciousness of God in our lives that helps us realize how much we desire and long for the rebuilding of our inner Jerusalem.
