From the beginning of being able to think independently, a person has a unique view and understanding of all things, and in different living environments, of course, it will also affect his thinking. What we think in our hearts, the subconscious mind dominates our behavior habits, and whether we can ultimately achieve an iron-hearted you or a kind-hearted you depends on your heart.
We usually hear people say that a certain person looks evil, and a certain person looks good and blessed, which may be the origin of the heart! In a limited life, it is still a kind and grateful person.
