To have empathy you must make an effort not only to have a different thinking, you must make an effort to think as a different being. You have to experience the being of another, through another world view/perspective. Neither observer nor observed. It is a deep connection through which both the observer and the observed journey together healing each another through the communal values: Respect for Nature, Wisdom, Patience, Freedom, Generosity and Compassion.
In ancient times All beings were able to communicate with each other without words.
