Our brain is “plastic”. It means that our brain’s structures and functions can change depending on how we use our mind. So, more we use our mind do things a certain way, more this way becomes the automatic way of doing in the future. This quality of “neuroplasticity” is the key focus of today’s neurosciences. It proves that we can (re)learn and cultivate some qualities of the mind to increase our happiness/well-being.
Mindfulness is a cornerstone of this change. Matthieu Ricard, an eminent scientist who worked for the Pasteur institute and who became a Buddhist monk elaborates in details on this topic in in his book Happiness: A Guide to Developing Life’s Most Important Skill.
