One can be grateful only when there is gratitude in his heart.
Every person has a different mind because one lives inside the mind world that he himself constructed by copying the things in this world.
Just as a copy of something is not authentic but is fake, people are incomplete because they live inside their false minds.
When you throw away your false, negative mind and become the universe mind itself that is real and true, you will come to have a positive mind. In turn you will have gratitude in your heart.
When you completely discard your false mind, you will come to know all the ways of the world and have no suffering or burden.
You will also come to have a positive mind and therefore will always have gratitude in your heart.
