What did Siddhartha Gautama see when he went out for hunting? What impression did it make on his mind?

When Siddhartha Gautama went out for hunting, he saw four sights which brought about an epiphany in his life. The first sight was of an old man who revealed to the prince the consequences of aging. Next, he saw a diseased man. On asking his accompanying charioteer, Channa, he was informed that every human being was subject to pain, ailments and suffering. The third important sight was that of a dead man, Siddhartha Gautama was informed that death was inevitable to all. He grew morose. Lastly, he came across an ascetic who had devoted his life in finding the cause of human suffering.

After watching the first three sights, Siddhartha Gautama realized the irrevocable nature of life which wasn’t free from the clutches of ailment, suffering and the inevitability of death. However, the sight of the dignified ascetic urged him to seek for the ultimate truth of life and the reason for human suffering. The sight signifies the means to outgrow pains to attain peace and calm. These four sights urged him to renounce human life.
