Throughout history, the primary agents of spiritual development have been the great religions. For the majority of the earth’s people, the scriptures of each of these systems of belief have served, in Bahá’u’lláh’s words, as “the City of God”, a source of a knowledge that totally embraces consciousness, one so compelling as to endow the sincere with “a new eye, a new ear, a new heart, and a new mind”. A vast literature, to which all religious cultures have contributed, records the experience of transcendence reported by generations of seekers. Down the millennia, the lives of those who responded to intimations of the Divine have inspired breathtaking achievements in music, architecture, and the other arts, endlessly replicating the soul’s experience for millions of their fellow believers. No other force in existence has been able to elicit from people comparable qualities of heroism, self-sacrifice and self-discipline. At the social level, the resulting moral principles have repeatedly translated themselves into universal codes of law, regulating and elevating human relationships. Viewed in perspective, the major religions emerge as the primary driving forces of the civilizing process. To argue otherwise is surely to ignore the evidence of history.
