sole purpose underlying their
revelation hath been to educate all men, that they may, at the
hour of death, ascend, in the utmost purity and sanctity and with
absolute detachment, to the throne of the Most High. The light
which these souls radiate is responsible for the progress of the
world and the advancement of its peoples. They are like unto
leaven which leaveneth the world of being, and constitute the
animating force through which the arts and wonders of the world
are made manifest. Through them the clouds rain their bounty upon
men, and the earth bringeth forth its fruits. All things must

God, both those of the former and recent times, present in the
heavenly assemblage.

The difference and distinction between men will naturally become
realized after their departure from this mortal world. But this
distinction is not in respect to place, but in respect to the soul
and the conscience. For the Kingdom of God is sanctified (or free)
from time and place; it is another world and another universe. And
know thou for a certainty that in the divine worlds the spiritual
beloved ones will recognize one another, and will seek union with
each other, but a spiritual union. Likewise a love that one may
have entertained for anyone will not be forgotten in the world of
the Kingdom, nor wilt thou forg
