Friday Nights Unplugged (8:59)

While most of us enjoy the physical, the same can't be said about the spiritual. The former is alluring and easy to relate to, but the latter requires much effort and inner struggle to appreciate. This is why G-d instructs us to combine them, as that creates the ultimate experience benefiting both body and spirit. Shabbat is a perfect example

Rabbi Abba Perelmuter (63)
