How can we remain unattached from this world?

Q: While living in this world, how can we remain unattached from the world?

A: While living in this world, you can stay unattached from it only if you understand this fact that the world is not true, whatever you are seeing is not true; the eyes with which you are seeing, the mind with which you are seeing, the brain with which you are watching the world; the brain, the mind, the eyes, the sensory organs, the body; this external world is not true. Then how can one attach oneself to this unreal world and be attached to it?
