【正确答案】 If taking a bath, appreciating a flower or eating a meal makes you feel happy, it is not because that the bath cleans you, the flowers are beautiful, or the food caters to your taste, but mainly because that your heart is free from preoccupations, and your soul is free enough to focus on the feeling of the flesh. If your spirit is low, everything will be like a farewell dinner. No matter how delicious it is cooked, it will still taste like soil or mud to you.
