The first noble truth of Buddhism is Dukkha – the truth of suffering. The Buddha came to comprehend that suffering comes in various ways. Three types of suffering relate to what the Buddha sighted in his initial journey outside the palace: sickness, old age, and death. Further, the Buddha realized that suffering extends much deeper and that life is never perfect – it regularly fails to remain up to expectations. The first noble is still relevant to the current world because when individuals do not suffer from external causes such as bereavement or illness, they are still unsatisfied, unfulfilled. Therefore, this is the open truth about suffering.
