[Emphasis added in the quotes below.]
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!
Be thou content with Me and seek no other helper. For none but Me can ever suffice thee.
(Baha'u'llah, The Arabic Hidden Words, No. 17)
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)
[In the following quote we see that being contented is not always good; Baha'u'llah gives us the divine criteria.]
O SON OF MAN!
Upon the tree of effulgent glory I have hung for thee the choicest fruits, wherefore hast thou turned away and contented thyself with that which is less good? Return then unto that which is better for thee in the realm on high.
(Baha'u'llah, The Arabic Hidden Words, No. 21)
O SON OF BEING!
Seek a martyr's death in My path, content with My pleasure and thankful for that which I ordain, that thou mayest repose with Me beneath the canopy of majesty behind the tabernacle of glory.
(Baha'u'llah, The Arabic Hidden Words, No. 45)
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 SON OF HIM THAT STOOD BY HIS OWN ENTITY IN THE KINGDOM OF HIS SELF!
Know thou, that I have wafted unto thee all the fragrances of holiness, have fully revealed to thee My word, have perfected through thee My bounty and have desired for thee that which I have desired for My Self. Be then content with My pleasure and thankful unto Me.
(Baha'u'llah, The Arabic Hidden Words, No. 70)
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 QUINTESSENCE OF PASSION!
Put away all covetousness and seek contentment; for the covetous hath ever been deprived, and the contented hath ever been loved and praised.
(Baha'u'llah, The Persian Hidden Words, No. 50)
O YE THAT PRIDE YOURSELVES ON MORTAL RICHES!
Know ye in truth that wealth is a mighty barrier between the seeker and his desire, the lover and his beloved. The rich, but for a few, shall in no wise attain the court of His presence nor enter the city of content and resignation. Well is it then with him, who, being rich, is not hindered by his riches from the eternal kingdom, nor deprived by them of imperishable dominion. By the Most Great Name! The splendor of such a wealthy man shall illuminate the dwellers of heaven even as the sun enlightens the people of the earth!
(Baha'u'llah, The Persian Hidden Words, No. 53)
I implore Thee, O Thou that turnest darkness into light, and revealest Thy mysteries on the Sinai of Thy Revelation, to aid me, at all times, to put my trust in Thee, and to commit mine affairs unto Thy care. Make me, then, O my God, content with that which the finger of Thy decree hath traced, and the pen of Thy ordinance hath written. Potent art Thou to do what pleaseth Thee, and in Thy grasp are the reins of all that are in heaven and on earth. No God is there but Thee, the All-knowing, the All-Wise."
(Baha'u'llah, Epistle to the Son of the Wolf, pp. 8-9)
