What inspired siddhartha spiritual quest?

Siddhartha Gautama, later known as the Buddha, was inspired to seek spiritual enlightenment after witnessing the suffering inherent in life, represented by the Four Sights: an old man, a sick man, a dead body, and a wandering ascetic. These experiences led him to question the nature of existence and the causes of suffering. Driven by a deep desire to find a solution to human suffering and achieve liberation, he embarked on a journey of self-discovery and meditation, ultimately leading to his enlightenment under the Bodhi tree.
