Love is light in whatsoever house it may shine

Life in this mortal world will quickly come to an end, and this earthly glory, wealth, comfort and happiness will soon vanish and be no more. Summon ye the people to God and call the souls to the manners and conduct of the Supreme Concourse. To the orphans be ye kind fathers, and to the unfortunate a refuge and shelter. To the poor be a treasure of wealth, and to the sick a remedy and healing. Be a helper of every oppressed one, the protector of every destitute one, be ye ever mindful to serve any soul of mankind. Attach no importance to self-seeking, rejection, arrogance, oppression and enmity.
Heed them not. Deal in the contrary way. Be kind in truth, not only in appearance and outwardly. Every soul of the friends of God must concentrate his mind on this, that he may manifest the mercy of God and the bounty of the Forgiving One. He must do good to every soul whom he encounters, and render benefit to him, becoming the cause of improving the morals and correcting the thoughts so that the light of guidance may shine forth and the bounty of His Holiness the Merciful One may encompass. Love is light in whatsoever house it may shine and enmity is darkness in whatsoever abode it dwell.
