O SON OF BEING! With the hands of power I made thee and with the fingers of strength I created thee; and within thee have I placed the essence of My light. Be thou content with it and seek naught else, for My work is perfect and My command is binding. Question it not, nor have a doubt thereof. - Baha'u'llah, The Arabic Hidden Words, No. 12
O SON OF MAN! If adversity befall thee not in My path, how canst thou walk in the ways of them that are content with My pleasure? If trials afflict thee not in thy longing to meet Me, how wilt thou attain the light in thy love for My beauty? - Baha'u'llah, The Arabic Hidden Words, No. 50
O COMPANION OF MY THRONE! Hear no evil, and see no evil, abase not thyself, neither sigh and weep. Speak no evil, that thou mayest not hear it spoken unto thee, and magnify not the faults of others that thine own faults may not appear great; and wish not the abasement of anyone, that thine own abasement be not exposed. Live then the days of thy life, that are less than a fleeting moment, with thy mind stainless, thy heart unsullied, thy thoughts pure, and thy nature sanctified, so that, free and content, thou mayest put away this mortal frame, and repair unto the mystic paradise and abide in the eternal kingdom for evermore. - Baha'u'llah, The Persian Hidden Words, No. 44
O SON OF SPIRIT! Ask not of Me that which We desire not for thee, then be content with what We have ordained for thy sake, for this is that which profiteth thee, if therewith thou dost content thyself. - Baha'u'llah, The Arabic Hidden Words, No. 18
