When Moses saw and approached the burning bush, God instructed him “take your shoes off..” and it was done to disconnect Moses from the Malchut level and elevate him to a dimension that he can see the future.
The Zohar tells us that God showed him the two Holy Temples that were destined for destruction because of man’s sins against the system.
God also revealed to him the last Temple, which will be greater than the two before, as it said in Haggai 2:9 “The future splendor of this temple will be greater than that of former times…and in this place I will give peace.” and in Zechariah 2:9 “…And will be unto her a wall of fire round about and I will be the glory in the midst of it.”
The fire wall is to protect from the Erev Rav because at the end of the Tikkun God will bring down the last Temple completed to sit permanently on the “middle point”. This is the “Return to Zion” שיבת ציון, that the whole world should be looking for. With this understanding everyone should be a part of this “Zionism”. The desire to complete the process that God showed Moses at the event of the Burning Bush should be part of every soul alive.
On the final return it is written in Jeremiah 31:8 “They will come with weeping; and with supplications will I lead them…” and Jeremiah 31:11 “And they shall come and sing in the height of Zion ….and their soul shall be as a watered garden, and they shall not know sorrow any more”
