Wert thou to attain to but a dewdrop of the crystal waters
of divine knowledge, thou wouldst readily realize that true life is not the
life of the flesh but the life of the spirit. For the life of the flesh is
common to both men and animals, whereas the life of the spirit is possessed
only by the pure in heart who have quaffed from the ocean of faith and partaken
of the fruit of certitude. This life knoweth no death, and this existence is
crowned by immortality. Even as it hath been said: “He who is a true believer
liveth both in this world and in the world to come.”
- Baha’u’llah (‘The Kitab-i-Iqan’)
