Cesar Millan said this quote

Spiritual fulfillment doesn't have to mean belief in a religion or disbelief in science. ... Whether one believes in an unseen, all-knowing force, or the wonder of science and the universe, or simply the beauty of the human spirit, nearly every one of feels an inner longing to feel part of something bigger than ourselves.

~ Cesar Millan

I believe in integrity. Dogs have it. Humans are sometimes lacking it.

~ Cesar Millan

I'll believe it if I see it for dogs translates to I'll believe it if I smell it. So don't bother yelling at them; it's the energy and scent they pay attention to, not your words.

~ Cesar Millan

Mother Nature's ruthless to the weak, but isn't arbitrary cruel or negative. Mother Nature saves aggression for extreme situations, and instead uses consistent leadership--to help keep things running smoothly. Mother nature doesn't rule by fear and anger, but by calm strength and assertiveness.
