Confine your troubles to a box. Put them there for safekeeping. Put a lock on it and peer inside from time to time when you need a reminder of why you came to this life on earth. Place a label on the box: “My life lessons”, then sit back and stare at the box. Ponder its contents from afar. How have you chosen to deal with them? How have you allowed them to change the course of your life, to affect your emotions, your health, and your relationships? Sitting back like this, pondering your box of troubles from afar, you are safe. They are safely tucked away and cannot affect you. In this state you can be peaceful, allowing your troubles to simply sit there locked away, harmless and neutral.
Now, will you open that box again? Of course you will. Your life lessons are in there. But know that at any time you are completely free to shut the lid again, click the lock, sit back, and observe that harmless box from that place of peace that is always there for you to sit in. Go there often—at will—and you will be far more peaceful for it.
