If you give your life as a prayer, you intensify the prayer beyond all measure. To attain inner peace you must actually give your life, not just your possessions. When you at last give your life bringing into alignment your beliefs and the way you live, then, and only then, can you begin to find inner peace.
"The mountains, the rivers, the whole earth, the entire array of phenomena are all oneself." If you can absorb the essence of this message, there are no activities outside of meditation: you dress in meditation and eat in meditation; you walk, stand, sit, and lie down in meditation; you experience joy, anger, sadness, and happiness in meditation.
