The light of truth has heretofore been seen dimly through variegated glasses, but now the splendors of Divinity shall be visible through the translucent mirrors of pure hearts and spirits. The light of truth is the divine teaching, heavenly instruction, merciful principles and spiritual civilization. Since my arrival in this country I find that material civilization has progressed greatly, that commerce has attained the utmost degree of expansion; arts, agriculture and all details of material civilization have reached the highest stage of perfection, but spiritual civilization has been left behind. Material civilization is like unto the lamp, while spiritual civilization is the light in that lamp. If the material and spiritual civilization become united, then we will have the light and the lamp together, and the outcome will be perfect. For material civilization is like unto a beautiful body, and spiritual civilization is like unto the spirit of life. If that wondrous spirit of life enters this beautiful body, the body will become a channel for the distribution and development of the perfections of humanity. ‘Abdu’l‑Bahá, The Promulgation of Universal Peace.
