(1) The Baal Shem Tov’s Torah on Yehudim meaning Mesiras Nefesh and it all began with Bnei Yisroel- Torah!

(2) The Rebbe’s notes on the Ba’al Shem Tov’s teaching. Mesiras Nefesh for a virtual year; denying Idolatry IS accepting all the Torah מה לי קטלא כולא מה לי קטלא פלגא. Two Yuds- Yetzer Tov and Yetzer Ra.

(3) This is a form of serving Hashem בכל דרכיך דעיהו on the highest level: Mesiras Nefesh.
