until one gains enlightenment.

+Just as a precious jewel, the sky, and water are by nature pure, likewise the
+tathagatagarbha or dharmadhatu is by nature always free from the defilement of
+the mental poisons and thus utterly pure. Whereas this is the meaning of the
+essence, the cause that completely purifies the adventitious defilements
+consists of devotion towards the Mahayana Dharma, of highest discriminative or
+analytical wisdom realizing the non-existence of a self, of limitless samadhi
+endowed with bliss, and of great compassion focusing on sentient beings as its
+point of reference. The realization arising from these [purifying causes] is
+to be known as enlightenment.
