Truthfulness is the foundation of all the virtues of mankind

May you become as the waves of one sea, stars of the same heaven, fruits adorning the same tree, roses of one garden in order that through you the oneness of humanity may establish its temple in the world of mankind, for you are the ones who are called to uplift the cause of unity among the nations of the earth.

Every kind of knowledge, every science, is as a tree: if the fruit of it be the love of God, then is it a blessed tree, but if not, that tree is but dried-up wood, and shall only feed the fire

When a man turns his face to God he finds sunshine everywhere.

To oppose knowledge is ignorant, and he who detests knowledge and science is not a man, but rather an animal without intelligence. For knowledge is light, life, felicity, perfection, beauty and the means of approaching the Threshold of Unity. It is the honor and glory of the world of humanity, and the greatest bounty of God. Knowledge is identical with guidance, and ignorance is real error

Close investigation will show that the primary cause of oppression and injustice, of unrighteousness, irregularity and disorder, is the people's lack of religious faith and the fact that they are uneducated.

Never is it the wish of `Abdu'l-Bahá to see any being hurt, nor will He make anyone to grieve; for man can receive no greater gift than this, that he rejoice another's heart. I beg of God that ye will be bringers of joy, even as are the angels in Heaven.
