You could say that meditating allows us to be more present in our everyday lives. We become less likely to be stuck in worrying about the future or dwelling over the past, instead living in this very moment most presently, making the most of the only tangible time: that which is in your hands right now.
Don't feel you have to jump into a formal seated meditation; you can get great results from the simple methods just as much as the more formal methods.
This book is about helping you find the right practice. It explains some of the concepts around meditation and mindfulness enabling you to bring the calm and ease of the practice into your day.
