Mindfulness is often spoken of as the heart of Buddhist meditation. It’s not about Buddhism, but about paying attention. That’s what all meditation is, no matter what tradition or particular technique is used.
My father was a world-class scientist and my mother was a prolific painter. I could see that my parents had completely different ways of knowing and understanding the world, and relating to it. My father approached things through scientific inquiry and exploration, while my mother experienced things through her emotions and senses.
When you pay attention to boredom it gets unbelievably interesting.
Mindfulness is so powerful that the fact that it comes out of Buddhism is irrelevant.
