O my loving friends! Consort with all the peoples and kindreds and religions of the world with the utmost truthfulness, uprightness, faithfulness, kindliness, good-will and friendliness; that all the world of being may be filled with the holy ecstasy of the grace of Baha, that ignorance, enmity, hate and malice may vanish from the world and the darkness of estrangement amidst the peoples and kindreds of the world may be turned into the light of unity. Should other peoples and nations be unfaithful show fidelity unto them, should they be unjust be just unto them, should they avoid you attract them, should they show enmity be friendly, should they poison you sweeten their lives, should they inflict a wound upon you be a salve to their sores. Such are the attributes of the sincere! Such are the attributes of the truthful! ...
