A game can never be played until you have a position,

A mind without game never work.totally depends on rational thinking.

same here

In life there is nothing wrong and nothing right.

It’s a consequence of rational thinking. that involves the duality.

A person never acts until it takes one side of the game.

Life lives on life.
As life is food of another life.

if you live.
you take one side of the game.
you are a monster for another one.which one is your food.

Religion provides you a structured map and guidance ,and lots of rules .

and what is the role of this game.

and Now you provide lots of rules to play the game of life ,and the mind starts working on that.

there is no devil.Devil is another people’god.
