Guitar, and all other instruments, is a physical process first. The physical is controlled by the hippocampus of the brain. That process is converted to the intellectual processes of our brains (right and/or left). Both are ongoing or at the moment.
Get the physical first. The brain will handle the rest. Everyone has heard of the "lightbulb" moment, or it just clicked. Get the physical first. There are many views to learn modes. Learning what is, will clear up, what ain't.
