There’s a traditional saying that the mind takes the shape it rests upon; the modern update is that the brain takes the shape the mind rests upon. For instance, if you regularly rest your mind upon worries, self criticism, and anger, then your brain will gradually take that shape – will develop neural structures and dynamics of anxiety, low sense of worth, and prickly reactivity to others. On the other hand, if you regularly rest your mind upon, for example noticing you’re all right right now, seeing the good in yourself and letting go…then your brain will gradually take the shape of calm strength, self confidence, and inner peace.”– Just One Thing, Rick Hanson writes
Summing it all up, friends, I’d say you’ll do best by filling your minds and meditating on things true, noble, reputable, authentic, compelling, gracious—the best, not the worst; the beautiful, not the ugly; things to praise, not things to curse. Put into practice what you learned from me, what you heard and saw and realized. Do that, and God, who makes everything work together, will work you into his most excellent harmonies (Philippians 4:8,9 MSG).
