August 25

If thou seekest eternal glory, let thyself be humble and meek in the presence of the beloved of God; make thyself the servant of all, and serve all alike. The service of the friends belongs to God, not to them. Strive to become a source of harmony, spirituality and joyfulness to the hearts of the friends and the maid-servants of the Merciful. This is a cause of great satisfaction to Abdul-Baha.
