Buddha Nature
Khyongla Rato Rinpoche

We and all sentient beings in this world share the potential to reach a state free from the gross and subtle obscurations. This shared potential is called Buddha Nature. It is possible to bring about this transformation because our consciousness is not in the nature of those obscurations: since it lacks inherent existence it is possible to transform it.
