The Sabbath was created as a time of rest from creation and the work of this world.  A time to worship and reflect on things of God. Consider this as part of your Sabbath:

“One should not think about the things of God when one’s stomach is full. There can be no vision of the Divine mysteries on a full stomach .” St. Seraphim of Sarov, 1754 – 1833 [Adapted]
