The Second Noble Truth

When Siddhartha was exploring the world, he noticed why the people were suffering. People suffer because of thir cravings and desire, or in other words, a personal attachment. These people suffer from a longing that is gone, or can no loger be obtained. This ails the people. So the second noble truth is the cause of suffering. This second noble truth is known as the Tahna. People are attached to things that they should let go of  and that is what is causing them all the pain.
