The lack of separation between mind and body should be obvious to us all. But for some reason, many people separate the two. Your brain is a physical thing, comprised of cells structures and chemical/electromagnetic activity; just like most of the rest of your body.
We all know that when we are emotionally excited, (our thoughts are the causation for our emotional states), our body changes ( heart-beat quickens, hormone rates change, sexual organs change, perspiration rates increase etc etc). And we know that when we are physically energised or tired, our thoughts are likewise influenced. Mind and body are inextricably entwined, and also one and the same thing.
Much Indian and Chinese philosophy has long recognized those interrelationships. The Indian practices of the various forms of yoga and the Chinese practices of the martial arts, Chi Gong and Tai Chi are all examples of mechanisms that promote calmness and centering through focussed bodily movement.
Combining your meditation practice with body movement practices can not only be physically healthy , but can also, over time, improve your capacity to focus your mind and develop your sense of calmness and “centredness”.
As with any physical activity, practicing moderation with mindfulness will ensure you do not overdo things, and damage muscles or bones!
