"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.
There is no authentic and sincere spiritual life without faith, hope and love; but there is no faith, hope, and love without mystical experience or, what is the same thing, without grace.
