“It—the body—is like a horse which carries the personality and spirit, and as such should be well cared for so it can do its work! You should certainly safeguard your nerves, and force yourself to take time, and not only for prayer and meditation, but for real rest and relaxation. We don’t have to pray and meditate for hours in order to be spiritual.“

– From a letter written on behalf of Shoghi Effendi, Prayer and Devotional Life
