Because all sentient beings have Buddha Nature, all we need for liberation and enlightenment are peace and clarity. Peace is the absence of afflicted emotions; clarity is the empty luminosity of the mind.
Enlightenment is not a supernatural state; it does not make us better, higher, or holier. It is our essential reality. There is no “secret way”, no “most powerful practice”. All practices –“high” and “low”– are simply methods to release afflicted emotions and rest the attention on luminous clarity. They are skillful means.
In truth, they are merely descriptions of what happens spontaneously when we recover our natural state. The “higher practices” are not something “we” do.
