Why does Krishna contradict himself in the Bhagwad Gita?

Krishna says he neither likes anybody nor does he dislike anybody. On the other hand he says some people are very dear to me.

That is Krishna’s specialty, to speak all the opposites and create confusion. 

At different levels of existence and for different incidences he says these statements and both are true.

On one level he says people who are calm, compassionate, happy and loving, I like them the most. So, you are most dear to me - this is true. 

Another time he says, don’t take me for granted, I have no likes and dislikes. Everyone is dear to me and I see myself in everyone.

The Bhagavad Gita is the most contradictory book you will ever read and it is the complete truth because it is so contradictory.

Achieving world peace

World peace can be achieved when people become ready to help each other. All of us belong to one family. Everybody should be able to say: ‘Whenever you are in need, I am with you’. 

There is a fear among people that no one would help them when they are in need. This is the sole reason for all the corruption and violence. People have somehow lost this trust. People have lost faith in themselves, in the Divine and in the society. 

There must be faith in the goodness of people in the society. People must have faith in themselves and faith that the Divine is taking care of us. If a person has faith in all the three, it will bring peace to them and also to the society.
