The meaning of this is that any individual who, before the expiry of a full thousand years—years known and clearly established by common usage and requiring no interpretation—should lay claim to a Revelation direct from God, even though he should reveal certain signs, that man is assuredly false and an impostor.
This is not a reference to the Universal Manifestation, for it is clearly set forth in the Holy Writings that centuries, nay thousands of years, must pass on to completion, before a Manifestation like unto this Manifestation shall appear again.
It is possible, however, that after the completion of a full thousand years, certain Holy Beings will be empowered to deliver a Revelation: this, however, will not be through a Universal Manifestation. Wherefore every day of the cycle of the Blessed Beauty is in reality equal to one year, and every year of it is equal to a thousand years.
Consider, for example, the sun: its transit from one zodiacal sign to the next occurreth within a short period of time, yet only after a long period doth it attain the plenitude of its resplendency, its heat and glory, in the sign of Leo. It must first complete one full revolution through the other constellations before it will enter the sign of Leo again, to blaze out in its full splendour. In its other stations, it revealeth not the fullness of its heat and light.
