The wisdom of the appearance of the spirit in the body is this: the human spirit is a Divine Trust, and it must traverse all conditions, for its passage and movement through the conditions of existence will be the means of its acquiring perfections.
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-BaháIf religion becomes a cause of dislike, hatred and division it were better to be without it.
Abdu'l-BaháThe spirit does not need a body, but the body needs spirit, or it cannot live. The soul can live without a body, but the body without a soul dies
Abdu'l-BaháWe ask God to endow human souls with justice so that they may be fair and may strive to provide for the comfort of all that each member of humanity may pass his life in the utmost comfort and welfare. Then this material world will become the very paradise of the Kingdom this elemental earth will be in a heavenly state and all the servants of God will live in the utmost joy happiness and gladness. We must all strive and concentrate all our thoughts in order that such happiness may accrue to the world of humanity.
Abdu'l-Bahá
