No man shall attain the shores of the ocean of true understanding except he be detached from all that is in heaven and on earth. Sanctify your souls, O ye peoples of the world, that haply ye may attain that station which God hath destined for you and enter thus the tabernacle which, according to the dispensations of Providence, hath been raised in the firmament of the Bayán. (Baha’u’llah, ‘The Kitab-i-Iqan’)
