Teshuvah is everything and Torah is everything. Light of the Torah shines till the end of the earth. Sefer Devarim is intermediary between the Oral Law and the Written Torah which takes place on Simchas Torah. Every Torah learned is the dance of Hashem dancing with His People. Holiest thing is to dance without moving. Everything was said to Moshe at Har Sinai. The mikvah in that mysterious room is where the rain waters and the waters from the faucet kiss. We purify ourselves by bringing the rain water from Hashem and the faucet water from people together.
