Episode notes
Brain Hemispheres Attend Differently
- The left hemisphere focuses on narrow, goal-oriented attention while the right hemisphere attends broadly and vigilantly.
- This difference creates two experiential realities: fragmented and utilitarian versus connected and meaningful.
Left Brain Denies, Right Brain Connects
- The left hemisphere associates with denial and control, often causing anxiety when control is lost.
- The right hemisphere provides happiness through community, nature, and sacred connection.
Right Brain as True Master
- The right hemisphere is the true master because it holds a broader and more accurate perception of reality than the left.
- The left often jumps to delusional conclusions, whereas the right guides with better social, emotional, and cognitive intelligence.
