'Africa to America' - Walter Heath

i came across this song/slideshow presentation today.  it depicts the agonizing story of slavery and ends with the birth of emancipation through the healing Message of Baha'u'llah.

"To know this is not enough. All knowledge is good, but it can bear no fruit except by action. It is well to know that riches are good, but that knowledge will not make a man rich; he must work, he must put his knowledge into practice. We hope the people realize and know that unity is good, and we also hope that they will not be content to stand still in that knowledge. Do not only say that Unity, Love and Brotherhood are good; you must work for their realization."

~ Abdu'l-Baha, Abdu'l-Baha in London, p. 59
