O ye members of the spiritual assembly! Become ye firm and steadfast in the Covenant and Testament to such a degree that your meeting become the expression of one soul and endeavor ye with your hearts and minds so that ye may become the cause of the illumination of this darkened world and that through your efforts the lights of the Kingdom dawn upon this nether sphere.
- ‘Abdu’l-Baha (From a Tablet to the Spiritual Assembly of New York; ‘Tablets of ‘Abdu’l-Baha, vol. 2)
