In this class on Sichos HaRan 65 and 66, we discuss the importance of simcha and how it can fend off negative forces which cause the death of children r"l, the curtailing of our dreams, and the spark of life to disappear from the eyes of our youth. We learn about a way to invest all of our physical and emotional energy into tefillah, awakening the "thunder" that can reveal the innate joy we hold within our hearts.
