People live in this world according to their minds.
They speak and live according to as much as they have in their minds.
The mind is formed by the habits that one is born with at birth, along with the karma formed during one's life lived. The unchangeable human mind world is one's selfish, narrow mind.
One needs to completely destroy his false mind world in order to change to the mind of the living God of this great universe.
Thereafter, you can live an improved life because you will know the princiles of the world and have wisdom.
