The book HaYom Yom, from Day to Day, daily is a source of deep insights that I find very profound...from Shabbos, 29 Adar II, 5765 - April 9, 2005:
(The 6th grand rabbi of Lubavitch hassidim notes a comment by his father , the 5th grand rabbi...)
My father said at a farbrengen (a gathering of hassidim): G-d created the universe and all physical objects Yeish Mei'ayin, something from nothing. Jews must transform the "something" into "nothing," transform the material into spiritual.
The Avoda (holy work) of turning the physical into spiritual and making the physical into an instrument for the spiritual, is a personal obligation. Every single person, individually, is required to do this.
What an entry! To elevate the mundane, the physical, literally into the spiritual. What an ability, what a responsibility!
The story is told, in the time to come, if a person passes and is involved with Torah and mitzvot, in holy purposes, good, if not, the rock and the ground itself will cry out "You clod, what right do you have to tread on me?"
