The soul is the breath of God in every human and the mind is our consciousness of our perception of existence. To  have the holy spirit is to know how to make the difference between what  is right and wrong The light and the darkness the right and the wrong  the good intuition and the doubt the real and the illusion. It  is to sum up to recognize that God has said of truth and of good and to  follow him and to abstain from what he has forbidden and recognized as  evil. Whoever educates his soul with good and gives him good principles  purifies it ; he who inculcates the bad choices corrupt him. The  holy spirit feeds on science and the knowledge of what comes from  heaven by learning from God through his books and prophets.
