Read the passage and answer the question:

On a particular day, Siddhartha convinced his charioteer to accompany him into the city, marking his inaugural venture into the world beyond the palace walls. This initial exposure proved to be distressing for him. The sight of an elderly individual, an ailing person, and a lifeless body filled him with profound sorrow.
