More about yourself, your Craft and the world around you. Some people seem to think that these 2 words are interchangeable. They are not. Knowledge is what you know. You gain knowledge through various forms of study.
Wisdom is something else entirely.
It is something that can not be taught. It is that which you gain through experience and intuition. Combine your knowledge with your wisdom. This seems to be something of a challenge as many of us have busy lives. This means creating balance in your life.
