One righteous act is endowed with a potency that can so elevate the dust as to cause it to pass beyond the heaven of heavens. It can tear every bond asunder, and hath the power to restore the force that hath spent itself and vanished.... Be pure, O people of God, be pure; be righteous, be righteous.... (Baha’u’llah, quoted by Shoghi Effendi in ‘The Advent of Divine Justice)
