On one occasion ‘Abdu’l-Bahá said to us,
At present rocks and thornbushes surround the Shrine of the Báb, but in the future this place will be encompassed by an abundance of trees and flowers and will be visited by all the peoples of the world. This Shrine you are viewing now will soon be expanded and its construction completed. In the future a kind of electrical power will be discovered which gives light from stone, and eventually the walls of the Shrine will be composed of such stone.
