Krishna explains the difference between the material and spiritual worlds to Arjuna. The material world is temporary, full of ignorance and misery, and is the reflection of the spiritual world, which is eternal, full of knowledge and bliss. In the material world, our pure love for Krishna becomes perverted into lust for sense gratification. Krishna tells Arjuna that one should live detached from material possessions and relationships, which are all impermanent, and focus on returning to the spiritual world by taking shelter of Krishna.
