The Legend of the Dragon Heart
Growing from a chicken heart into a Lion heart was only the first step of a long journey. To keep one's mind open is to keep learning every day, day after day. Then, one needs to keep one's heart open to keep growing.
If one's heart is open for long enough, it will grow and be light to, one day fly away as a dragon heart. That's the journey of the lion.
Now that we are a dragon heart, what's next? To unlearn to learn again. To change shape to have more fun and more power. To fly was only the beginning.
