Ba’al Hatanya (Sha’ar Hayichud Ve’emunah) – the entire world is held up by the very letters of creation. Chida – why is it actually necessary for us to utter the words when we pray; what happens when you rearrange the letters? Nefesh Hachayim – Your name after death. Did you “live” the letters of your name? The Ba’al Shem Tov’s letter.
