If you want to end your suffering, long standing negative thoughts and if you want to improve yourself then must read book
It helps us to see actually how to ease our suffering, also it helps us to look into our thoughts and its consequences. Trust me before reading this book I was in so much confusion and unstable mind but after reading this I really felt whatever thinking i was doing is just waste of time and it drains my energy. Very helpful if you are facing stress, anxiety, breakdown and thinking too much.
