"There is a town with eleven gates belonging to the Unborn (Brahman), whose thoughts are never crooked. He who approaches it, grieves no more, and liberated (from all bonds of ignorance) becomes free. This is that.
In plain words: The body is like a town with eleven gates, the body's openings, where Brahman, the Unborn, lives. Brahman's thinking is never crooked. Whoever turns to it stops grieving and becomes truly free.
