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
For tantric rigpa is the knowledge of the essence of energy, the secret sound.
Most esoteric traditions agree that thoughts themselves are not the enemy. On the other hand, when we are thinking, awareness is dulled and confused.
Thoughts and emotions are different. In Buddhism the word namtog encompasses both.
