"I am blind and do not see the
things of this world; but when the light comes from above, it enlightens my
heart and I can see, for the Eye of my heart sees everything; and through this
vision I can help my people. The heart is a sanctuary at the center of which
there is a little space, wherein the Great Spirit dwells, and this is the Eye.
This is the Eye of the Great Spirit by which He sees all things, and through
which we see Him. If the heart is not pure, the Great Spirit cannot be
seen." – Nicholas Black Elk
