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-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-BaháIf you desire with all your heart, friendship with every race on earth, your thought, spiritual and positive, will spread; it will become the desire of others, growing stronger and stronger, until it reaches the minds of all men.
Abdu'l-Bahá
