The five types of deep awareness refer to Buddha-nature factors, which we all have that enable us to achieve the state of a Buddha – the various Buddha Bodies. In general, these five types of deep awareness are the basic ways with which we experience things, the basic mechanism of how our mental activity works. When fully developed, they become features of the omniscient, all-loving mind of a Buddha – the Deep Awareness Dharmakaya. It’s only on the basis of correctly understanding voidness, that our various types of deep awareness can be valid in all ways.
