The power of words is that our knowledge of them commands how and what we think because we can only think concretely about things of what we have words to describe.
The magic of words is that they are artists that explode vibrant paint onto the canvas of our imagination. Think of the most beautiful words you have heard. It might be beauty, or sacred, or reverence, or maybe God, or perhaps space. Remember how these words imbue your entire being with a story, with an emotion or an inspiration that craves your longing. Cherish the words that are dearest to you. Guard them from the corruption of vileness.
These are the indescribable power and magic of words.
