It should, moreover, be born in mind that 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 fulfill his or her life's
purpose.
