"Let integrity and uprightness distinguish all thine acts."

"Be generous in prosperity, and thankful in adversity. Be worthy of the trust of thy neighbor, and look upon him with a bright and friendly face. Be a treasure to the poor, an admonisher to the rich, an answerer of the cry of the needy, a preserver of the sanctity of thy pledge. Be fair in thy judgment, and guarded in thy speech. Be unjust to no man, and show all meekness to all men. Be as a lamp unto them that walk in darkness, a joy to the sorrowful, a sea for the thirsty, a haven for the distressed, an upholder and defender of the victim of oppression. Let integrity and uprightness distinguish all thine acts."

"Know ye not why We created you all from the same dust?"

Shrine of Bahá’u’lláh

"O Children of Men!
Know ye not why We created you all from the same dust? That no one should exalt himself over the other. Ponder at all times in your hearts how ye were created. Since We have created you all from one same substance it is incumbent on you to be even as one soul, to walk with the same feet, eat with the same mouth and dwell in the same land, that from your inmost being, by your deeds and actions, the signs of oneness and the essence of detachment may be made manifest. Such is My counsel to you, O concourse of light! Heed ye this counsel that ye may obtain the fruit of holiness from the tree of wondrous glory."

‘Akká

"O Son of Spirit!

I created thee rich, why dost thou bring thyself down to poverty? Noble I made thee, wherewith dost thou
abase thyself? Out of the essence of knowledge I gave thee being, why seekest thou enlightenment from anyone beside Me? Out of the clay of love I molded thee, how dost thou busy thyself with another? Turn thy sight unto thyself, that thou mayest find Me standing within thee, mighty, powerful and self-subsisting."

"O Son of Spirit!

The best beloved of all things in My sight is Justice; turn not away therefrom if thou desirest Me, and neglect it not that I may confide in thee.
