"The world is continually proclaiming these words: Beware, I am evanescent, and so are all my outward appearances and colours."

"Happy is the faithful one who is attired with the vesture of high endeavour and hath arisen to serve this Cause. Such a soul hath truly attained the desired Goal and hath apprehended the Object for which it hath been created. But a myriad times alas for the wayward who are like unto dried-up leaves fallen upon the dust. Ere long mortal blasts shall carry them away to the place ordained for them. Ignorant did they arrive, ignorant did they linger and ignorant did they retire to their abodes.

The world is continually proclaiming these words: Beware, I am evanescent, and so are all my outward appearances and colours. Take ye heed of the changes and chances contrived within me and be ye roused from your slumber. Nevertheless there is no discerning eye to see, nor is there a hearing ear to hearken.

In this Day the inner ear exclaimeth and saith: Indeed well is it with me, today is my day, inasmuch as the Voice of God is calling aloud. And the essence of vision crieth out: Blessed am I, this is my day, for the Ancient Beauty is shining resplendent from the most exalted Horizon.

It behoveth the people of Bahá to invoke and entreat the Lord of Names that perchance the people of the world may not be deprived of the effusions of grace in His days."
