The human spirit may be likened to the bounty of the sun shining on a mirror. The body of man, ... grows and develops through the animal spirit.
Abdu'l-BaháThe confirmations of the Spirit are all those powers and gifts which some are born with (and which men sometimes call genius), but for which others have to strive with infinite pains. They come to that man or woman who accepts his life with radiant acquiescence.
Abdu'l-BaháObserve that the body of man is confined to a small place; it covers only two spans of earth. But the spirit and mind of man travel to all countries and regions - even through the limitless space of the heavens - surround all that exists, and make discoveries in the exalted spheres and infinite distances. This is because the spirit has no place; it is placeless; and for the spirit the earth and the heaven are as one since it makes discoveries in both.
Abdu'l-BaháThis 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-BaháAll down the ages we see how blood has stained the surface of the earth; but now a ray of greater light has come, man's intelligence is greater, spirituality is beginning to grow, and a time is surely coming when the religions of the world will be at peace. ...let us join together to hasten forward the Divine Cause of unity, until all humanity knows itself to be one family, joined together in love.
Abdu'l-Bahá
