The soul in a word, is your Conscience.
Soul - The animating and vital principle in humans, credited with the faculties of thought, action, and emotion and often conceived as an immaterial entity.
Conscience - motivation deriving logically from ethical or moral principles that govern a person's thoughts and actions
One synonym for soul is - personality - the complex of all the attributes--behavioral, temperamental, emotional and mental--that characterize a unique individual; "their different reactions reflected their very different personalities"; "it is his nature to help others"
