We Indians do not teach that there is only one god.  We know that everything has power, including the most inanimate, inconsequential things.  Stones have power.  A blade of grass has power.  Trees and clouds and all our relatives in the insect and animal world have power.  We believe we must respect that power by acknowledging it's presence.  By honoring the power of the spirits in that way, it becomes our power as well.  It protects us.

One is expected to know things, to believe things.  Knowing and believing are all in your head - there is nothing in your heart.  If you cannot feel that the earth is your grandmother, then of course you will find it easy to rape her, to behave as if she is under your dominion.  You will find it easy to believe that we humans are the dominant species, and to act as though the earth and everything on it are ours to do with as we please.  … if all human beings were taken away, life on earth would flourish.
