Meditation, martial arts that focus on disciplining the mind as well as the body, and chi-releasing massage and yoga can all help you reach your goals by clearing your mind, teaching you how to block out distractions, and showing you how to deal effectively with obstacles. The disciplines of Eastern mind-body arts are a great help when stress or outside influences threaten your progress, and the meditative mindset helps keep the link between the sub-conscious and conscious mind open, streamlining the flow of creativity and flexibility and promoting the intelligent use of internal resources - and, not incidentally, short circuiting some of the resistance and negative self-talk that often create failure where there was none before.
Following a regimen of meditation and mind-body-spirit exercises also has a tendency to bring up old, suppressed issues and emotions that could be blocking forward movement without you even realizing it. Just think of these issues as psychological and emotional computer viruses lurking in your "hard drive", quietly and invisibly throwing all sorts of otherwise normal functions off kilter, sometimes dangerously, and even protecting themselves by creating negative thought patterns which not only prevent you from removing them, but which prevent you from even seeing them in the first place. Yoga, meditation, deep prayer, hypnotic chants and other reflective practices are sort of like virus scanners that can root out such problems, bring them to the surface and isolate them more or less safely in a "quarantine" of conscious awareness where you can study them and their effects, and then get rid of them, in your own time.
