Everything in life is dukkha
The Buddha taught that everything in life is dukkha. Dukkha literally means pain, misery or suffering. However, the experience of the truth of dukkha is much deeper than a feeling of sorrow or contemplation about suffering. It is the direct understanding of the impermanence of the nåmas and rúpas in our life and the realization that none of these phenomena is true happiness. Some people may think that pondering over this truth is already the experience of the truth of dukkha. However, one does not have the real understanding of the truth if one merely thinks about it. When paññå has been developed to the degree that the arising and falling away of nåma and rúpa are directly understood, one will come to realize the truth of dukkha. Then one will gradually learn to be less attached to nåma and rúpa.
