Plants are more courageous than almost all human beings: an orange tree would rather die than produce lemons, whereas instead of dying the average person would rather be someone they are not.
Intelligence is more important than strength, that is why earth is ruled by men and not by animals.
Every creature was designed to serve a purpose. Learn from animals for they are there to teach you the way of life. There is a wealth of knowledge that is openly accessible in nature. Our ancestors knew this and embraced the natural cures found in the bosoms of the earth. Their classroom was nature. They studied the lessons to be learned from animals. Much of human behavior can be explained by watching the wild beasts around us. They are constantly teaching us things about ourselves and the way of the universe, but most people are too blind to watch and listen.
