Siddhartha had encountered four events in his life that led him to leave his palace and seek answers to the “pain of existence”. The first insight which he encounters was a man bent with old age, the second insight was a person who was afflicted with sickness, the third insight was of a corpse, and the last insight was of a wandering ascetic. The fourth insight pushed Siddhartha to find out a way for the solution to the pain of existence. So, after encountering all of these events he left all the luxuries of his life and left his palace (The Life Of The Buddha, 2013).
