Free from doubt

"Examine the wondrous behaviour of the Prophets, and recall the defamations and denials uttered by the children of negation and falsehood, perchance you may cause the bird of the human heart to wing its flight away from the abodes of heedlessness and doubt unto the nest of faith and certainty, and drink deep from the pure waters of ancient wisdom, and partake of the fruit of the tree of divine knowledge. Such is the share of the pure in heart of the bread that hath descended from the realms of eternity and holiness."

-- Baha'u'llah, The Book of Certitude
