The utterance of God is a lamp, whose light is these words: Ye are the fruits of one tree, and the leaves of one branch. Deal ye one with another with the utmost love and harmony, with friendliness and fellowship. He Who is the Day Star of Truth beareth Me witness! So powerful is the light of unity that it can illuminate the whole earth. The one true God, He Who knoweth all things, Himself testifieth to the truth of these words.
Exert yourselves that ye may attain this transcendent and most sublime station, the station that can ensure the protection and security of all mankind. This goal excelleth every other goal, and this aspiration is the monarch of all aspirations. So long, however, as the thick clouds of oppression, which obscure the day star of justice, remain undispelled, it would be difficult for the glory of this station to be unveiled to men’s eyes....
- Baha’u’llah (‘Gleanings from the Writings of Baha’u’llah’)
