"Though the worlds of God be infinite, yet some refer to them as four ..."

"Secrets are many, and strangers are myriad. Volumes will not suffice to hold the mystery of the Beloved, nor can it be exhausted in these pages, though it be no more than a word, no more than a sign. “Knowledge is one point, which the foolish have multiplied.”⁴⁸

Infer, then, from this the differences among the worlds. Though the worlds of God be infinite, yet some refer to them as four: the world of time, which hath both a beginning and an end; the world of duration, which hath a beginning but whose end is not apparent; the world of primordial reality, whose beginning is not to be seen but which is known to have an end; and the world of eternity, of which neither the beginning nor the end is visible. Although there are many differing statements as to these points, to recount them in detail would result in weariness. Thus some have said that the world of primordial reality hath neither beginning nor end, and have equated the world of eternity with the invisible, inaccessible, and unknowable Essence. Others have called these the worlds of the Heavenly Court, of the Celestial Dominion, of the Divine Kingdom, and of Mortal Existence."
