Be 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-BaháEvery 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-BaháTo oppose knowledge is ignorant, and he who detests knowledge and science is not a man, but rather an animal without intelligence. For knowledge is light, life, felicity, perfection, beauty and the means of approaching the Threshold of Unity. It is the honor and glory of the world of humanity, and the greatest bounty of God. Knowledge is identical with guidance, and ignorance is real error
Abdu'l-Bahá
