“The Dolphin Principle. Living Riding the Wave” is a book by Alexander and Nicole Gratzowski.
In it, the authors explain that dolphins have unique abilities and that there’s much we can learn from them.
The Gratzowskis spent a lot of time with dolphins on their expeditions and understood that dolphins are constantly involved in what’s going on—they only do what brings them joy, and they don’t pretend. If they love, it’s unconditionally; if they’re not friends, it’s forever.
