These affirmations help you bring your attention inside and above your head where meditation occurs. You can use them to awaken the inner energy or to help yourself to get into meditation. Say each one a few times silently inside, with sincerity. Using these exact words is not as important as the meaning, say what feels right to you.
Make your self comfortable before starting, take a few deep breaths and relax. Use your right hand and put it on the left side of your body. Try and bring your attention to where your hand is while you say the affirmation. In that way your attention will also rise as your hand does.
