I can draw a 'euphoric warmth' into my body straight from thin air. It’s the same euphoria you feel after a good workout, known as a runner's high. As you well know, that warm, pleasant feeling isn’t just your body warming up after exercise—it’s a wave of joy and vitality that starts in your chest and spreads throughout your body, lifting your spirits. We actually feel different versions of this warmth in all sorts of happy moments: soaking up the sunshine, hugging someone we love, or being blown away by an amazing piece of art. In this preface, I'll show how these seemingly unrelated experiences are actually different forms of the same thing— all originating from a single source: God. Surprisingly, everything that makes life breathtakingly beautiful and gives us goosebumps can be traced all the way back to before the Big Bang. However, this profound existential insight is not going to be the book's most crucial aspect. What's really fascinating is that even while perfectly still in a dark and freezing room, without any external stimuli or another person, I can generate this same blissful warmth within a few breaths. You might've heard about monks who can sit on ice for hours without getting cold. Well, this isn't some superhuman ability— it's the power of true meditation, way beyond anything you'll get from a meditation app. That's the reason why monks often choose to be alone: to fully experience this nourishing energy and melt into it for days and nights. However, I believe this warmth is not something to be kept only for oneself; it is a gift meant to be shared and turned into something even greater. So, in my part of the story, I’m excited to share this book with all of you, explaining everything as clearly and simply as possible—from how these experiences connect to God, to how you can tap into this cosmic source of euphoria yourself. You are welcome to share it with friends, neighbors or even your local barista. My hope is that it reaches those who need it most.
