To maintain a healthy body requires exercise, proper nutrition and sleep.  To have a healthy mind requires that we keep it active with mental exercises like solving puzzles and riddles.  What about the soul?  Does it need maintenance?  Yes, of course.
    Your soul need to be maintained in three primary ways.  Exercise your soul by communicating with angels and other Beings of Light.  "Lubricate" your soul by doing good deeds, especially helping others to develop their spiritual side.  Feed your soul with the spiritual Light from God.  Once a soul is awakened, it must be cared for or it will be lost to the forces of darkness.
