Human brain is constantly working, which means it works 24 hours a day. That is why it should be directed to constructive and quality thoughts. Most people think about their day and what that day brought them both good and bad. It is necessary to understand what caused what happened to you, especially if it is repeated in the same or similar way. Until you understand the reason and learn a life lesson from that event, it will keep repeating itself. This means that you go around in circles and actually live in the past and do nothing to change your life or improve your life situation. It’s not good for you, and it’s not good for others.
People have the ability to shape themselves and grow spiritually by thinking. Spiritual growth has nothing to do with religion but with God. God is not a religion.
