Jesus still goes a bit further with "Do not let your left hand know what your right is doing." At least, my brain thinks he did. Of the other measures Jesus called you and me to take to ensure that we don't mess it up, this one is pretty messed up and borderline impossible. To do this, literally, you have to ensure that all the thoughts and thinking involved in moving your right hand don't even cross to the other side of your brain. Our brains have two hemispheres, and each hemisphere controls the opposite side of the body. These hemispheres are bridged through the corpus callosum, lobes, brainstem, cerebellum, and others.
