"May no trace of self be detected from their conduct and manners, from their words and deeds. Man’s greatness lieth in humility, and his abiding glory is found in lowliness, self-effacement, and servitude to the servants of the Lord."

 
... "I beseech and entreat the all-pervasive grace of the Most Bountiful Lord to grant that the hearts of His loved ones may become the repositories of divine inspiration and the daysprings of the effusions of His limitless bounty, so that, with the utmost harmony and fellowship, they may all be freed from the estrangement of the realm of vainglory and may associate with one another with perfect humility and lowliness. May no trace of self be detected from their conduct and manners, from their words and deeds. Man’s greatness lieth in humility, and his abiding glory is found in lowliness, self-effacement, and servitude to the servants of the Lord. This, verily, is the greatest attainment in this resplendent Day.

Thou hast asked concerning the blessed verse “From the heaven to the earth He ordereth all things, and hereafter shall they come up to Him on a day whose length shall be a thousand of such years as ye reckon.”¹⁴⁹ By this “day” is meant the Day of the Great Resurrection, the Day of Judgement, for on that Day there shall appear such signs and events, such splendours and occurrences, marvels and wonders, truths and mysteries, precepts and writings, that the revelation of those splendours and signs cannot be contained even in fifty thousand years. Moreover, the precepts and laws, and the writings, teachings, and manifold bounties associated with that Day, which is none other than the “appointed time of a known day”,¹⁵⁰ shall remain valid and binding for a full thousand years, nay for five hundred thousand years. Such a span of time is merely an approximation that alludeth to ages and centuries. And on that appointed Day, the outpourings of divine grace shall visibly descend from the kingdom of mercy and the heaven of oneness. And as such outpourings of grace cannot endure forever in this nether world, that glorious light must needs return to the luminous Star from whence it came, and those merciful showers that emanate from the liberal effusions of the sea of oneness must return, once again, to the Most Great Ocean." ...
