All aspects of the universe are subject to constant change, continually moving in the direction of enlightenment. Change but provides the doorways through which all must travel to find true 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.
