The children must be carefully trained to be most courteous and well-behaved. They must be constantly encouraged and made eager to gain all the summits of human accomplishment, so that from their earliest years they will be taught to have high aims, to conduct themselves well, to be chaste, pure, and undefiled, and will learn to be of powerful resolve and firm of purpose in all things. Let them not jest and trifle, but earnestly advance unto their goals, so that in every situation they will be found resolute and firm." ʻAbdu'l-Bahá, Selections from the Writings of Abdu'l-Bahá, p.
