Here is an excerpt from my book, SEVEN STEPS TO INNER POWER, where I discuss the creative power of your words:
When you have let go of negative emotions during your shower meditation and are making your first impressions on the new day, be sure to use positive affirmations. Let your inner and outer dialogue with yourself be filled with positive declarations about your true self. Instead of saying, "I am not sad," be sure to affirm positives such as "I am full of the confidence and natural joy of my real self."
It's always important to consider the way we communicate and the words we use, whether in daily life, in our meditations or in our inner dialogue One of the most powerful avenues of expression your mind uses is your words. Consider for a moment how you think. Don't you generally "hear" yourself think? You express your ideas in words, words that either play in your mind or words you speak out loud.
Words have great creative power. Your words can tear someone down or inspire them to be a hero. Your words can spur someone to greater achievements or get them fired. Since words are the creative carriers of your mental energy, treat them with great respect and choose them carefully with all your heart. Be conscious of what you are saying. If you have to, pause before you speak. Careful means "full of care." I encourage you to send your words out with extreme care because with those words you can start World War III in your relationships. We've all had the experience of saying something we didn't mean and finding that the words, once released, go right ahead and have an effect, maybe one we didn't intend.
It's not so much the word itself that has an effect but the energy and vibration the word carries as you say it - your intent. The energy and intent you put behind your words makes all the difference. So when you're speaking to others as well as to yourself, examine what energy you are letting your words carry. Are you building up your ego in a selfish way that hurts others are are you boosting another's self-image? If a woman keeps telling her husband how stupid he is, he can start to believe that and decide that "if I can't do anything right, why bother trying at all?" In your dialogue with others and in your own inner dialogue, constantly reflect on whether you are paralyzing yourself and others or whether you are elevating yourself and others.
