The nature of reality and the nature of nature is vibration, waves. As a wave, everything, including our bodies are a process/vibration/movement rather than a 'thing'. All waves have peaks and valleys, but they are one whole process; undivided. This is the nature of waves.
Emotions are waves with interdependent peaks and valleys. While we have little control over the waves of emotions or choices of others, we can still our own wave and joyfully ride the waves of human experience from a place of stillness and non-duality. By stilling (not controlling) our emotional waves (non-attachment), we can 'influence' the waves of others rather than getting pulled into or attuning to the dramatic waves of the world. In stillness there is peace.
Shadow integration work is aimed at stilling our wave, releasing the emotional charge and peacefully riding the waves of life through all its peaks and valleys, its births and deaths.
