Question: After the exodus from Egypt, the Torah was received, which represents the special holiday of Shavuot. Receiving the Torah means receiving the upper light with the help of which a person can correct himself and reach the level of the Creator.
Why did this happen on Mount Sinai?
Answer: Mount Sinai personifies hatred toward our egoism, due to which we can receive the highest light.
We received the method for correcting the ego because we hated it as we were standing under Mount Sinai, we saw how much this selfishness is odious to us, how much it is against us. We were literally ready to bury ourselves under this mountain if we did not receive the force of correction.
Only after that were we able to enter the Land of Israel, in Eretz Yisrael.
“Eretz” is desire, “Israel” (Isra-El)—aimed directly to the Creator (Yashar-Kel).
Being in the Land of Israel, we built the First and the Second Temples there, which personify the unification of the whole soul in its leading form, called Israel. And in our time, we must draw to this not only ourselves, but also the whole humanity and reach the Third Temple.
