Gautama was married to a princess called Yashodhara at the age of sixteen and had a son named Rahula. One evening, while he was passing through the city, he came across an old man who had been abandoned by his relatives, a sick man crying in pain, and a dead body surrounded by grieving relatives. He was deeply affected by all these miseries. In 537 BCE, Gautama left his palace and went to the forest in search of truth. He attained enlightenment while meditating under a pipal tree near the city of Gaya.
