What is the previous sentence of "It's better to have a good mouth"

I discovered that I have a good heart.

I discovered that it is better to have a good mouth than to have a good heart. There are two things in this world that cannot be looked at directly, the sun and the human heart. Because good intentions are never as good as good words. In today's society, today's people like the false and don't like the truth. What you can do is not as good as what you can say, and what you can say is not as good as how to pretend.

My heart is free of dust and my mind is at peace. Troubles arise from the mind. If you think too little about the same thing, you will be worry-free, but if you think too much, you will be asking for trouble. For the same question, when you see the bright side, you feel happy, and when you see the dark side, you feel sad. The joy and sorrow of life does not lie in how many things you encounter, but in how many things you hold in your heart. Be simpler, be more positive, and you will naturally have fewer worries. Empty the haze in your heart. Only when your heart is pure can your mind be calm, and only when your mind is calm can you feel comfortable.
