Are your thought processes creating guilt, pride, resentment, anger, regret, or self-pity? Then you are not only reinforcing a false sense of self but also helping to accelerate your body's aging process by creating an accumulation of past in your psyche. Verify this for yourself by observing those around you who have a strong tendency to hold on to the past.
Die to the past every moment. You don' t need it. Only refer to it when it is absolutely relevant to the present. Feel the power of this moment and the fullness of Being. Feel your presence.
Are you worried? Do you have many "what if" thoughts? You are identified with your mind, which is projecting itself into an imaginary future situation and creating fear. There is no way that you can cope with such a situation, because it doesn't exist. It's a mental phantom. You can stop this health- and life-corroding insanity simply by acknowledging the present moment. Become aware of your breathing. Feel the air flowing in and out of your body. Feel your inner energy field. All that you ever have to deal with, cope with, in real life - as opposed to imaginary mind projections – is this moment. Ask yourself what "problem' you have right now, not next year, tomorrow, or five minutes from now. What is wrong with this moment? You can always cope with the Now, but you can never cope with the future -nor do you have to. The answer, the strength, the right action or the resource will be there when you need it, not before, not after.
