Reflect that light is the expression of the vibrations of the etheric matter: the nerves of the eye are affected by these vibrations, and sight is produced. The light of the lamp exists through the vibration of the etheric matter; so also does that of the sun, but what a difference between the light of the sun and that of the stars or the lamp!

The spirit of man appears and is manifest in the embryonic condition, and also in that of childhood and of maturity, and it is resplendent and evident in the condition of perfection. The spirit is one, but in the embryonic condition the power of sight and of hearing is lacking. In the state of maturity and perfection it appears in the utmost splendor and brilliance. In the same way the seed in the beginning becomes leaves and is the place where the vegetable spirit appears; in the condition of fruit it manifests the same spirit—that is to say, the power of growth appears in the utmost perfection; but what a difference between the condition of the leaves and that of the fruit! For from the fruit a hundred thousand leaves appear, though they all grow and develop through the same vegetable spirit. Notice the difference between the virtues and perfections of Christ, the splendors and brilliance of Bahá’u’lláh, and the virtues of the Prophets of Israel, such as Ezekiel or Samuel. All were the manifestations of inspiration, but between them there is an infinite difference. Salutations!
