In the past, the brain was considered to be the ground of being and the mind an epiphenomenon of it. The brain existed as the primary ground and the mind the secondary ground.
The consciousness is now considered to be the ground of being and the brain the epiphenomenon. Consciousness is the primary ground not the brain as previously believed. Consciousness is a wave in the quantum field and the body is as a particle within it so is subject to the effect of wave function collapse meaning its position and orientation within the quantum field can be influenced by the consciousness which can, therefore, change the body-brain-mind and so the future path of your life. In other words consciousness can induce the placebo effect.
