Fill your bowl to the brim and it will spill. Keep sharpening your knife and it will blunt. Chase after money and security and your heart will never unclench. Care about people's approval and you will be their prisoner. Do your work, then step back. The only path to serenity.
Who can enjoy enlightenment and remain indifferent to suffering in the world? This is not in keeping with the Way. Only those who increase their service along with their understanding can be called men and women of Tao.
