“Before the experience of Mount Sinai, the coarse material of which the world is made could not be elevated. It could be used as a medium, an aid in achieving enlightenment, but it itself could not be enlightened. Jacob used sticks for meditation. Isaac dug wells. But neither the sticks nor the wells became imbued with G-dliness. 

All that changed at Mount Sinai. When you take a piece of leather and write upon it a Torah scroll, you have transformed the material into spiritual. And the same with flour used for matzah for Passover night, and branches used to cover a succah, and even the earnings which you tithe for good causes.  And so you may do in every aspect of your life.” ~ R’ Tzvi Freeman
