The core of Buddhism is the Buddha’s teaching on the Four Noble Truths. The truth of misery is first noble truth. It means that suffering is an intrinsic part of life. It pervades the whole of our life. It is real, not illusory. It is of two broad categories. There is first the physical or biological experience of pain. Birth itself is a suffering and is the gateway for other sufferings like disease, old age and death. Then there are the mental and psychological forms of suffering: distress arising out of separation from our loved ones, loss of things or people, grief over torture or persecution, failures or frustrated desire, the impermanence of pleasure. Thus physical and mental sufferings are woven into the fabric of our existence. Not that there is no joy and happiness at all in life; but they are all short-lived. Suffering dominates life.
