The heart must needs… be cleansed from the idle sayings of men, and sanctified from every earthly affection, so that it may discover the hidden meaning of divine inspiration, and become the treasury of the mysteries of divine knowledge. Thus hath it been said: “He that treadeth the snow-white Path, and followeth in the footsteps of the Crimson Pillar, shall never attain unto his abode unless his hands are empty of those worldly things cherished by men.” This is the prime requisite of whosoever treadeth this path. Ponder thereon, that, with eyes unveiled, thou mayest perceive the truth of these words.
- Baha'u'llah ('The Kitab-i-Iqan')
