To me, the word wisdom means ancient knowledge. It's the kind of knowledge you not only see but feel when you look into the eyes of an elephant or stop for a moment to marvel at the deep wrinkles on its skin, both of which I believe contain the truths learned from each intentional step their feet and those of their ancestors have placed upon the earth.
