Two gems

"We cannot segregate the human heart from the environment outside us and say that once one of these is reformed everything will be improved. Man is organic with the world. His inner life moulds the environment and is itself also deeply affected by it. The one acts upon the other and every abiding change in the life of man is the result of these mutual reactions."

"The principle of the Oneness of Mankind - the pivot round which all the teachings of Baha’u’llah revolve – is no mere outburst of ignorant emotionalism or an expression of vague and pious hope. Its appeal is not to be merely identified with a reawakening of the spirit of brotherhood and good-will among men, nor does it aim solely at the fostering of harmonious cooperation among individual peoples and nations. Its implications are deeper, its claims greater than any which the Prophets of old were allowed to advance. Its message is applicable not only to the individual, but concerns itself primarily with the nature of those essential relationships that must bind all the states and nations as members of one human family. … It implies an organic change in the structure of present-day society, a change such as the world has not yet experienced. … It calls for no less than the reconstruction and the demilitarisation of the whole civilized world — a world organically unified in all the essential aspects of its life, its political machinery, its spiritual aspiration, its trade and finance, its script and language, and yet infinite in the diversity of the national characteristics of its federated units."
