" Reality is not divisible; it does not admit multiplicity."

"I hope that the lights of the Sun of Reality will illumine the whole world so that no strife and warfare, no battles and bloodshed remain. May fanaticism and religious bigotry be unknown, all humanity enter the bond of brotherhood, souls consort in perfect agreement, the nations of earth at last hoist the banner of truth, and the religions of the world enter the divine temple of oneness, for the foundations of the heavenly religions are one reality. Reality is not divisible; it does not admit multiplicity. All the holy Manifestations of God have proclaimed and promulgated the same reality. They have summoned mankind to reality itself, and reality is one. The clouds and mists of imitations have obscured the Sun of Truth. We must forsake these imitations, dispel these clouds and mists and free the Sun from the darkness of superstition. Then will the Sun of Truth shine most gloriously; then all the inhabitants of the world will be united, the religions will be one, sects and denominations will reconcile, all nationalities will flow together in the recognition of one Fatherhood, and all degrees of humankind will gather in the shelter of the same tabernacle, under the same banner.

Until the heavenly civilization is founded, no result will be forthcoming from material civilization, even as you observe. See what catastrophes overwhelm mankind. Consider the wars which disturb the world. Consider the enmity and hatred. The existence of these wars and conditions indicates and proves that the heavenly civilization has not yet been established. If the civilization of the Kingdom be spread to all the nations, this dust of disagreement will be dispelled, these clouds will pass away, and the Sun of Reality in its greatest effulgence and glory will shine upon mankind."
