1st sight- A decrepit old man leaning on his staff as he walked.
2nd sight- A sick man suffering in pain and soiled by incontinence brought on by his infeebled condition.
3rd- sight- A human corpse being carried to a funeral pyre.
4th sight- A calm, ascetic monk with a clean shaven head wearing a yellw robe.
The sum of those images struck Sidhartha with the force of a revelation: All humans are subject to suffering.
Transformed by the insight, he dcided to leave home in search of a solution to the problem of human suffering. Thus began what is known as "the Great Renunciation". Sidhartha's abdication of a princely life in favor of one as a wandering ascetic in selfless denial of material possesions.
