It involves abstaining from work and other activities on the seventh day of the week, which is traditionally considered to be a day of rest. The term RESTS, which is a five-letter solution to the crossword, is an appropriate description of this practice, as it implies taking a break from the hustle and bustle of everyday life in order to observe the Sabbath.
