This perfected body can be compared to a mirror, and the human spirit to the sun. Nevertheless, if the mirror breaks, the bounty of the sun continues; and if the mirror is destroyed or ceases to exist, no harm will happen to the bounty of the sun, which is everlasting. This spirit has the power of discovery; it encompasses all things.
Abdu'l-BaháAn humble man without learning, but filled with the Holy Spirit, is more powerful than the most nobly-born profound scholar without that inspiration. He who is educated by the Divine Spirit can, in his time, lead others to receive the same Spirit.
Abdu'l-BaháThe mind and spirit of man advance when he is tried by suffering. ... so suffering and tribulation free man from the petty affairs of this worldly life until he arrives at a state of complete detachment.
Abdu'l-BaháTo promote knowledge is thus an inescapable duty imposed on every one of the friends of God.
Abdu'l-BaháChrist is ever in the world of existence. He has never disappeared out of it.... Rest assured that Christ is present. The Spiritual beauty we see around us today is from the breathings of Christ.
Abdu'l-BaháWhat profit is there in agreeing that universal friendship is good, and talking of the solidarity of the human race as a grand ideal? Unless these thoughts are translated into the world of action, they are useless. The wrong in the world continues to exist just because people only talk of their ideals, and do not strive to put them into practice. If actions took the place of words, the world's misery would very soon be changed into comfort.
Abdu'l-Bahá
