I have a special interest in training the mind to reduce negative thoughts and emotions with meditation exercises. I was therefore curious to find out if this book could give me some useful insights on this point.
It does. In emotions we depend on two competing systems. The "low road" or fast system that is very similar for all vertebrae animals and "high road" slow system that adds the Cortex for thinking into the circuit. That thinking capability is most strongly developed in the human species. The low road -slow systems follows the following steps:
Emotional stimulus -Sensory Thalamus - Amygdala -Emotional response
The competing parallel, slow system with half the speed has an additional link as follows:
Emotional stimulus- Sensory Thalamus-Sensory Cortex- Amygdala- Emotional response
The fast system is the best in case of real danger requiring instant reaction. But it can create trouble when a reaction is triggered by a false alarm leading to the wrong reaction. The slow system involving the Cortex evaluates the emotional stimulus, considers the context, and examines the options before deciding on the reaction and thus avoiding wrong reactions. It also has learning capability. Mistakes are not repeated. Training the mind will strengthen the influence the Cortex will have on the reaction. When I feel a sudden burst of anger, I now realise that it is probably the result of the fast road short-circuiting the Cortex circuit. So I pause to gain control of my anger.
The second useful idea is that memory of past experiences colour our views without us being aware of it. For example I had a bad experience working with a fast talker that turned out to be unreliable. The next time I met a fast talker I was instantly negative to that person without being aware why. I now ask myself before taking a position. Am I prejudiced?
The third point is awareness of the enormous advantage humans have of having a large fore brain that allows us instead of reacting automatically to emotional stimulus being able to make plans, analyse risk and analyse consequences. Analytical meditation strengthens this planning and evaluation capability.
The fourth point is that I understand better why it is so hard to reduce egocentric tendencies. The fast circuit is excellent for survival because it leads to instant action. But survival reactions without thinking only consider my survival without considering the consequences of my actions on others. Bringing the "primitive" system under control is therefore hard work.
The fifth point is the irreparable damage excessive continuous stress does to the memory system in the Hippocampus. That illustrates the merits of meditation to develop the ability to stay calm under high stress circumstances.
Complex systems are explained with excellent diagrams. The book may be a bit long for leaders in business, 300 pages. But, I think that the benefits make the effort to read it worthwhile. Understanding how your brain works helps you in training your mind
