The First Noble Truth, which points out that all things are suffering, tells us precisely what things are like. But we fail to realize that all things are a source of suffering and so we desire those things. If we recognized them as a source of suffering, not worth desiring, not worth grasping at and clinging to, not worth attaching ourselves to, we would be sure not to desire them. The Second Noble Truth points out that desire is the cause of suffering. People still don't know, don't see, dont understand, that desires are the cause of suffering. They all desire this, that and the other, simply because they don't understand the nature of desire. The Third Noble Truth points out that deliverance, freedom from suffering, Nirvana, consists in the complete extinguishing of desire. People don't realize at all that nirvana is something that may be attained at any time or place, that it can be arrived at just as soon as desire has been completly extinguished.
