In Tibetan we call the essential nature of mind Rigpa—primordial, pure, pristine awareness that is at once intelligent, cognizant, radiant, and always awake. This nature of mind, its innermost essence, is absolutely and always untouched by change or death. At present it is hidden within our own mind, our sem, enveloped and obscured by the mental scurry of our thoughts and emotions. Just as clouds can be shifted by a strong gust of wind to reveal the shining sun and wide-open sky, so, under certain circumstances, some inspiration may uncover for us glimpses of this nature of mind. These glimpses have many depths and degrees, but each of them will bring some light of understanding, meaning and freedom.

This is because the nature of mind is the very root itself of understanding.
