The essential oneness of all the myriad forms and grades of life is one of the fundamental teachings of Bahá’u’lláh. Our physical health is so linked up with our mental, moral and spiritual health, and also with the individual and social health of our fellowmen, nay, even with the life of the animals and plants, that each of these is affected by the others to a far greater extent than is usually realized. There is no command of the Prophet, therefore, to whatever department of life it may primarily refer, which does not concern bodily health. Certain of the teachings, however, have a more direct bearing on physical health than others, and these we may now proceed to examine. Simple Life ‘Abdu’l-Bahá says:— Economy is the foundation of human prosperity. The spendthrift is always in trouble. Prodigality on the part of any person is an unpardonable sin. We must never live on others like a parasitic plant. Every person must have a profession, whether it be literary or manual, and must live a clean, manly, honest life, an example of purity to be imitated by others. It is more kingly to be satisfied with a crust of stale bread than to enjoy a sumptuous dinner of many courses, the money for which comes out of the pockets of others. The mind of a contented person is always peaceful and his heart at rest.—Bahá’í Scriptures, p. 453. Animal food is not forbidden, but ‘Abdu’l-Bahá says:—“Fruits and grains [will be the foods of the future]. The time will come when meat will no longer be eaten. Medical science is only in its infancy, yet it has shown that our natural diet is that which grows out of the ground.”—Ten Days in the Light of Akká, by Julie M. Grundy. Alcohol and Narcotics The use of narcotics and intoxicants of any kind, except as remedies in case of illness, is strictly forbidden by Bahá’u’lláh. Enjoyments The Bahá’í teaching is based on moderation, not as asceticism. Enjoyment of the good and beautiful things of life, both material and spiritual, is not only encouraged but enjoined. Bahá’u’lláh says: “Deprive not yourselves of that which has been created for you.” Again He says: “It is incumbent upon you that exultation and glad tidings be manifest in your faces.” ‘Abdu’l-Bahá says:— All that has been created is for man, who is at the apex of creation, and he must be thankful for the divine bestowals. All material things are for us, so that through our gratitude we may learn to understand life as a divine benefit. If we are disgusted with life we are ingrates, for our material and spiritual existence are the outward evidences of the divine mercy. Therefore we must be happy and spend our time in praises, appreciating all things. Asked whether the Bahá’í prohibition of gambling applies to game of every description, ‘Abdu’l-Bahá replied:—
