What four sights changed Siddhartha life?

The four sights that profoundly changed Siddhartha Gautama's life were an old man, a sick person, a dead body, and an ascetic. These encounters exposed him to the realities of aging, suffering, and death, prompting deep reflection on the nature of existence. The sight of the ascetic, who had renounced worldly pleasures in pursuit of spiritual enlightenment, inspired Siddhartha to seek a path toward liberation from suffering. This journey ultimately led him to attain enlightenment and become the Buddha.
