Bahá’ís believe the crucial need facing humanity is to find a unifying vision of the future of society and of the nature and purpose of life. Such a vision unfolds in the writings of Bahá’u’lláh. The Bahá’í community of the United Kingdom is exploring Bahá'u'lláh’s spiritual teachings with people of all backgrounds and is learning how this vision of the oneness of mankind, best expressed by the principle of unity in diversity, can be translated into action for the betterment of the world.
