The lion spirit animal is generally associated with a representation of personal strength. If the lion appears powerful to you, its presence as a spirit guide can be interpreted as a positive representation of your self-confidence or personal power. As such, lions point to qualities of strength, courage, assertiveness.
Lions are also animals who dominate other animals in nature. Remember as an example the expression “the lion, king of the jungle”. When a lion appears as your power animal, it could reflect your ability to lead others or tendency to dominate in relationships or at work.
