Rigpa is the knowledge of the ground. Pure open/panoramic awareness; naked/empty vision. A Tibetan word meaning the “essential nature of mind”, or unchanging, transparent awareness.

Question: Can there be thinking during Rigpa (Buddha Mind)?
Answer: It is essential to resolve the fact that there is no namtog (thought) whatsoever in the state of rigpa; it is impossible. A hair cannot remain in a flame. I cannot emphasize this enough – there is no thought during the state of rigpa!
— As It Is, volume 2, p.168

Just remember transmission after Phat being in guru’s awake state not judging or thinking.

For tantric rigpa is the knowledge of essence of energy, the secret sound.

Thoughts and emotions are different. In Buddhism the word namtog encompasses both.
