Can bhavanga-consciousness be compared to the non-dual mind-state rigpa?

While reading Pa Auk Sayadaw I came across the following: > The bhavanga-consciousness is bright and luminous, and looks like a mirror in the heart: that is the mind-door. This seems to have qualities similar to: > In Dzogchen the fundamental, inherent nature of everything is called the "Ground Luminosity" or the "Mother Luminosity." Are these two qualities of mind related?
