There are 80 to 100 billion neurons in a human brain, and every single one of them can form thousands of connections with other neurons, leading to a complex network of hundreds of trillions of synapses that enable brain cells to communicate with each other.

Like a computer network built from five hundred trillion transistors, each representing a “bit” of information depending on whether it is “on” or “off.”

Rick Hanson, PhD

Yet, despite the best efforts and findings of modern neuroscience, the true functioning of our mind remains one of the greatest and most fascinating mysteries. We know a lot about how our brain helps us stay alive, communicate, and perceive the world around us. But this knowledge, however brilliant, continues to change at an extraordinary pace and represents only a tip of a gigantic iceberg whose full beauty is hiding well from our sight.

Is it then preposterous to consider that something as trivial as focusing our mind and breathing steadily for a short time every day could have a profound effect on our well-being? Is it in our power at all to make changes to our own brain?
