Know the self to be sitting in the chariot, the body to be the chariot, the intellect the charioteer, and the mind the reins. The senses they call the horses, the objects of the senses their roads. When he (the Highest Self) is in union with the body, the senses, and the mind, then wise people call him the Enjoyer.
