…although to be married is highly desirable, and Bahá'u'lláh has strongly recommended it, it is not the central purpose of life. If a person has to wait a considerable period before finding a spouse, or if ultimately, he or she must remain single, it does not mean that he or she is thereby unable to fulfil his or her life's purpose.
