Thou shouldst endeavour to study the science of medicine. It is is extremely useful and serveth as the greatest instrument for the dissemination of the Cause. It is absolutely imperative that thou acquire this bounty. Strive day and night that thou mayest become highly qualified in this science. And when thou wishest to dispense treatment set thy heart toward the Abhá Kingdom, entreating divine confirmations. ('Abdu'l-Bahá, The Compilation of Compilations, vol. I, Health, Healing and Nutrition)
