... you should not neglect your health, but consider it the
means which enables you to serve. 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.
- Shoghi Effendi (From a letter dated November 23, 1947 written on behalf of
Shoghi Effendi to an individual believer; printed in compilation: ‘Spiritual
Foundations’)
