Compassion suits our physical condition, whereas anger, fear and distrust are harmful to our well-being. Therefore, just as we learn the importance of physical hygiene to physical health, to ensure healthy minds, we need to learn some kind of emotional hygiene.
The right way to deal with mental unhappiness must be within the mind too. On an emotional level, anger, fear and worry bring unhappiness. Scientists say they eat into our immune system. On the other hand, we are also equipped with a sense of affection and compassionate concern for the well-being of others.
Too much of a self-centered attitude creates mistrust and suspicion in others, which can in turn lead to fear. But if you have more of an open mind, and you cultivate a sense of concern for others' well-being, then, no matter what others' attitudes are, you can keep your inner peace.
Depression seems to be related to fear, anger and frustration. When you're in a bad mood, even if you meet with your friends, you don't take pleasure in their company. But when you're in a good mood, even if things go wrong, you can cope with them without difficulty. This is why putting yourself in a good mood, making a point of developing a sense of loving kindness gives you greater inner strength.
Once your mind is calm and full of love, there is no room for hatred or fear. Others will trust you because of your open heart.
