Awareness and basic space are inseparable.
This single sphere is the basis for samsara and nirvana.
If we don't understand confused appearances as the potency of awareness,
we get stuck in the experience of samsara.
Awareness is transparent. Basic space is transparent.
To the Dzogchen yogi, all phenomena are clear appearances.
All that appears and exists within samsara and nirvana is the originally pure single sphere.
Driving the nail of one's own experience of this transparent wisdom into the ultimate sphere of samsara and nirvana, one gains certainty free from all doubts.
