The importance of a meditated lifestyle is the spiritual benefits. It's exercise for God's peace. Many are physically fit, but spiritually ill from lack of God's riches to allow a peaceful life for their indecent hearts.
Think on this: I benefit the justice of peace because I travel with God's righteous ways to peaceful treasures.
I traverse the way of righteousness, In the midst of the paths of justice, That I may cause those who love me to inherit wealth, That I may fill their treasures." --Proverbs: 8: 20 NKJV
