Have you ever been hurt and spent a long time afterwards reminding all your friends and acquaintances how miserable you felt? You all suffered about it and maybe you still do. 
The first time I heard about the concept that Suffering is Optional, I did not believe that it could possibly be true. Then I learned the difference between pain, which is all too real, and the option to not make it worse than it is and to choose to do something else instead.
I learned that if I kept replaying the memory of a former good friend treating me badly, I suffered. However, if I read a good book instead of replaying the memory, I felt much better. Sometimes I would remember, and the pain came back, but generally, I could control the situation.
Then I learned Logosynthesis and with 3 simple sentences, I drained all my energy out of the memory, and could remember what happened without any pain at all.
Then, suffering truly became optional. Now, if I keep thinking about any hurt, I use the process and get on with other things.
All the instructions you need to do the same are in this book. So, if you would like to make suffering optional for yourself, get your copy and get started right now.
