Therefore, they are so- called Ariya Saccani, The Noble Truths. The First Noble Truth deals with dukkha which means suffering or misery. Dukkha therefore means feeling of emptiness. An Ariya sees things as they truly are. To an Ariya all life is suffering and he finds no real happiness in this world which otherwise deceives mankind with illusory pleasures.
Material happiness is merely the gratification of some desire.
No one is exempt from these four causes of suffering. Unfulfilled wishes are also suffering. As a rule, every body wishes to be associated either with beloved persons or pleasant things. No body wishes to be associated with hated persons or unpleasant things. We always wish to be associated with persons or things we like.
