phagmo drupa says: by meditating on the one taste of all things, the meditator will cognize the one taste of all these things. the diversity of appearances and nonappearances, mind and emptiness, emptiness and non-emptiness, are all of one taste, undifferentiable in their intrinsic emptiness. understanding and lack of understanding are of one taste; meditation and nonmeditation are nondifferentiable; meditation and absence of meditation are unified into one taste; discrimination and lack of discrimination are one taste in the expanse of reality.
