If we practice identifying the causes of our suffering, we will see that sometimes is due to craving and sometimes it is due to other factors. To say, "Life is suffering," is too general. To say that craving is the cause of all our suffering is too simplistic. We need to say, "The basis for this suffering is such and such is an affliction." and then call it by its true name. IF we have a stomach ache, we need to call it a stomach ache. If it is a headache, we need to call it a headache. .... It is true that the Buddha taught the truth of suffering, but he also taught the truth of "dwelling happily in things as they are". To succeed in the practice, we must stop trying to prove anything. IF we touch the truth of suffering with our mindfulness, we will be able to recognize and identify our specific suffering, its specific causes, and the way to remove those causes and end our suffering.
