It takes great effort to build walls in order to protect or guide treasures of your heart such as your peace, but it takes almost nothing and only a few seconds to lose what you spend months, and possibly years building and protecting.
Masters of their art, and well developed minds have learned to not only invest in building walls guiding their treasured values against vain distractions and ethics but they also invest in increasing their consciousness to stay focused at every moment they may be vulnerable in losing what they have built to protect.
This isn’t about buildings and structures, this is really about focus, consciousness, consistency and sustainability.
