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
Abdu'l-BaháBe ye a refuge to the fearful; bring ye rest and peace to the disturbed; make ye a provision for the destitute; be a treasury of riches for the poor; be a healing medicine for those who suffer pain; be ye doctor and nurse to the ailing; promote ye friendship, and honour, and conciliation, and devotion to God, in this world of non-existence.
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-BaháLet's be wise as the silence, strong as the wind, useful as the light; let's make of our lips a censer of the virtues.
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
