I've posted elsewhere in the forums about fact that the analytical / rational neural network in the brain and the empathic / intuitive network cannot both be in use at the same time. https://www.medicalnewstoday.com/articles/252241.php Brain Can't Empathize And Analyze At Same Time, New Study More on brain networks on my web site: https://sites.google.com/site/chs4o8pt/meditation-1#meditation_brain_networks Meditation turns on the empathic / intuitive network which is one reason meditation can be a helpful practice in spiritual development and psychic development. I recently read an article about a similar phenomenon involving the sympathetic and parasympathetic nervous systems. The sympathetic nervous system is involved in producing the body's response to stress. The parasympathetic nervous system is involved in turning off the body's response to stress. Anything that activates the parasympathetic nervous system suppresses the sympathetic nervous system and helps you to relax. This is relevant to spiritual development because when you are stressed you are more likely to be thinking about yourself and your problems ie. being egocentric. But when you are relaxed, you are less likely to be thinking about yourself and more likely to be in harmony with spiritual values like love, kindness, forgiveness, tolerance etc. The article I read is here: http://healthvibed.com/relaxation-101-how-to-activate-the-pns It includes a discussion of methods of activating the parasympathetic nervous system ie. turning off stress. I've learned from doing yoga that exercises which involve gently stretching muscles while exhaling slowly are a very powerful way to turn off stress (ie activate the parasympathetic nervous system). I've found it's the best way to do it that I know of. Those kinds of exercises together with Meditation make up a very powerful system for spiritual development.
