Worry distorts reality, amplifying both joy and fear. Calm the mind by focusing on truth, not "what ifs." Paramhansa Yogananda's "worry fast" suggests mindful breaks of one hour at a time. Also, relax the body and then the mind by using tense-relax breathing, releasing all tension-creating thoughts. Furthermore, replace negative thoughts with positive memories to lift your mind to a higher consciousness, where worry ceases to exist.
Have faith in yourself, for you have the power to produce positive or negative realities. Focus on the long rhythm, not the short, in order to manifest positivity and live in the eternal now.
