Bahá’u’lláh taught that hearts must receive the Bounty of the Holy Spirit, so that Spiritual civilization may be established. For material civilization is not adequate for the needs of mankind and cannot be the cause of its happiness. Material civilization is like the body and spiritual civilization is like the soul. Body without soul cannot live. 
(‘Abdu'l-Baha, from a talk, September 30, 1911; ‘Abdu'l-Baha in London’)
