The Functioning of Consciousness Is Influenced by the Brain

Whenever the eighth consciousness manifests dharmas, the manas necessarily relies on the eighth consciousness to cognize them and to discern them. Even though the manas itself has no problem, if the brain has a problem, the manas cannot normally direct the movement of the whole body through the brain's nervous system, and the mind consciousness is also affected. Only after the brain functions normally can the mind consciousness think normally. Only when the brain is normal in later life can the manas's direction and control function normally, and the mental activity of the mind consciousness can also function normally.
