। ॥ १७१ ॥
In plain words
There is no such thing as ignorance apart from the mind. The mind itself is ignorance -- it is exactly what binds you to this worldly existence. Destroy the mind, and everything is destroyed with it. Let it expand, and the whole world expands right along with it.
Close to the Sanskrit
There is indeed no ignorance separate from the mind; the mind indeed is ignorance, the cause of bondage to worldly existence. When that mind is destroyed, everything is destroyed; when this mind expands, everything expands.
