If your Conscious Mind Aka Inner I is still, quiescent while holding a meditative state, it will be guided intuitively, producing true images flowing forth from one's true Self as Spirit. This is what Nikola means when he says the brain is a receiver.
If, however, your Inner I Aka Conscious Mind creates and conjures thought within itself, it veils Spirit while defiling the Subconscious Aka Human spirit, thereby producing egoic false images that give birth to separation and duality that causes both yourself and others to suffer due to being cut off from your true Self and each other.
Mind/body-Consciousness reveals life, it does not create it. Spiritual-Consciousness that flows through it, animating it does.
