Leo is represented by a lion. This lion was described in ancient mythology as being extremely violent and so Hercules killed this lion, taking its pelt as his payment for having killed it. The lion could be described as a powerful animal and yet, there is no energy of being powerful in this way on planet Earth. Humans have no fur--we freeze to death if we get wet or cold. Humans have no claws, no strength. If we fight with someone we become very vulnerable. Why do we describe ourselves as powerful? We are lying whenever we say it. By coincidence, powerful means the ability to do work. But most people I know who describe themselves as powerful are more in charge of getting others to work than they are of supporting people who are working.
