If… the spiritual nature of the soul has been so strengthened that it holds the material side in subjection, then does the man approach the Divine; his humanity becomes so glorified that the virtues of the Celestial Assembly are manifested in him; he radiates the Mercy of God, he stimulates the spiritual progress of mankind, for he becomes a lamp to show light on their path. 
- ‘Abdu’l-Baha  (From a talk, November 17, 1911, Paris; ‘Paris Talks’)
