Shalom and Blessing. Tonight, after last week’s understanding of internal peace bringing health to the body, we will learn about external peace, l’sheim shamayim, and the level of controversies that are for the sake of heaven. All of this will lead us to a deep understanding about the pulse of man and the pulse of the Universe, in Kabbalah. The Rebbe will also explain the importance of cleansing our blood and the effects on our spirit and the rest of the body.
