Chastity and purity of life are the two divine standards of the spiritual and moral law. The greater the aim of man the nobler his purpose. A man must ever be thoughtful of others and be polite and courteous toward his fellow-beings. This will win for him the good pleasure of the Lord and the satisfaction of the general public. One's sitting and rising, speech and conversation, social intercourse and communication should be based upon a firm foundation and be conducive to the glory of the world of humanity.
- 'Abdu'l-Baha (Words of Abdul-Baha, from the Diary of Mirza Ahmad Sohrab, September 4, 1913)
