The Upanishads are part of the Hindu scriptures. They include many metaphors and analogies. In one, a rider sits in a chariot, driven by a charioteer. The chariot represents the human body. The road the chariot travels on represents things that we perceive with our senses. The horses that pull the chariot represent the senses. The reins represent the mind, which controls the senses. The chariot driver represents the human mind or intuition. The owner of the chariot has full authority over the chariot, but does not need to do anything to direct it.
In this analogy, what do you think is represented by the owner of the chariot?
