In remote antiquity, there were men of divine enlightenment who were perfectly acquainted with the feelings and habits of all living things, and thoroughly understood the languages of the various species.

According to Lieh Tzu, the ancient sages understood all beings, from the spirits of Chinese tradition (the koei, chenn, li and mei) to birds and insects, for those who share the same blood and the same breath cannot be very different. Today, look kindly at an animal you come across, and try to understand what it is living.
