What are false unchanging entities?

I am having trouble with the concept of "unchanging entities which exist on their own". > Attachment to the false view of self means **belief in the presence of unchanging entities which exist on their own**... > *The Miracle of Mindfulness* p. 48 Questions: 1. What are some examples of "false ideas" of "unchanging entities that exist on their own"? 2. How do they contribute to the false view of self? Thank you all for your time.
