"A harsh word is even as a sword thrust; a gentle word as milk."

"O people! Words must be supported by deeds, for deeds are the true test of words. Without the former, the latter can never quench the thirst of the yearning soul, nor unlock the portals of vision before the eyes of the blind. The Lord of celestial wisdom saith: A harsh word is even as a sword thrust; a gentle word as milk. The latter leadeth the children of men unto knowledge and conferreth upon them true distinction.

The Tongue of Wisdom proclaimeth: He that hath Me not is bereft of all things. Turn ye away from all that is on earth and seek none else but Me. I am the Sun of Wisdom and the Ocean of Knowledge. I cheer the faint and revive the dead. I am the guiding Light that illumineth the way. I am the royal Falcon on the arm of the Almighty. I unfold the drooping wings of every broken bird and start it on its flight."
