In other words, the primordial state of enlightenment is discovered. Mind-essence was pre-enlightened; our original ground is already enlightened. In the Dzogchen approach, this discovery is called being re-enlightened. Mahamudra does not use these terms re-enlightened and pre-enlightened, but at the fourth stage of nonmeditatation the meaning is basically the same. ... Third is awareness-rigpa reaching fullness, and the fourth stage is called the exhaustion or depletion of all concepts and dualistic phenomena. This stage is equivalent of the stage of nonmeditation in Mahamudra. The ultimate state of enlightenment is being re-enlightened in the pre-enlightened original ground, as mentioned above.

The best situation would be if we had never strayed into the deluded way of perceiving to begin with. But somehow it seems that we missed the opportunity to be primordially enlightened, and now we are deep in confusion. ... Even though we missed the chance to be primordially enlightened - "pre-enlightened," if you will - we can still attain stability in the natural freedom of our essence and become "re-enlightened."
(Drubwang Rinpoche: Fearless Simplicity, p. 95)
We possess an enlightened essence, but having temporarily lost that connection we are deluded. Continuously missing the opportunity to awaken, we fall under the power of our ordinary experience, governed by habits so strenuous to maintain such a clinging to a self. ... The loosening of our grasping untangles a knot in our heart; we do not need to stay bound and strangled by it. Likewise, from our confused state, we can be reprogrammed because we are primordially enlightened and we have the potential to return to that state as re-enlightened. Best to leave this for now and conclude by using Tulku Urgyen Rinpoche's words: ... The dirt has to be removed to re-establish the purity of the jewel.
