The primordially pure essence of the fundamental state is all-pervading emptiness.

The nature of this primordial purity is ever present and inseparable from appearance – so that timeless emptiness and temporal appearances are never divided but always non-dual.

It is only because of this that buddhas manifest when the natural state is realised, whereas sentient beings manifest when it is not.
