Grails - validation of incoming data and the persistent instance

In reading "The Definitive Guide To Grails 2", I am trying to understand the grails validation mechanism. The book states that if a type error occurs during validation then:

Grails automatically sets the persistent instance to read-only so it cannot persist unless you yourself explicitly make it persist...

What is this persistent instance? Is it the domain object instance that I might be about to try to save to persistent storage?
