I have to say a HUGE THANK YOU to my grandfather Reb Yosef Wineberg a"h as today I learned something from his explanation of Tanya that is HUGE.We – our body which in a sense is our actual self (for we identify with it) is neutral (composite of both holy and unholy parts/desires) when I do a Mitzvah (follow Go/-od ) this elevate me into the realm of holiness and each and every Mitzvah brings into me an infinite lightIn the flip side if I G-d forbid sin (do something contrary to the will of G-d and even simply waste time) I denigrate myself(IN fact I bring a stain onto my soul which is rectified though Teshuvah – changingThis is kind of life itself!
