This isn't a course about mindfulness. It's training in mindfulness. The difference matters.
You can read an entire book about swimming and still not know how to swim. You can know the biomechanics of freestyle perfectly — arm position, breathing technique — and still sink the moment you get in the water. Mindfulness works the same way. Knowing what it is changes nothing. Practicing it does.
In the coming lessons, you're going to learn by doing. There will be explanations, but only as support for the practice. The heart of this course isn't what you read here — it's what happens when you close the laptop and sit down to practice.
