Your son will grow up to be either a Great King or a Great Holy Leader
He was born as Siddhartha Gautama in the 6th century to a royal family in Nepal
After his birth, a holy man predicted that Siddhartha would either be a religious teacher or a great King
To prevent Siddhartha from turning to religion and to ensure that he would become King, his father made his life as desirable as possible and protected him from the suffering in the world.
After 49 days he achieved Great Enlightenment and became a Buddha. He discovered that the only way to avoid suffering is to free yourself from desires.
At 80 years old Buddha announced that he would soon reach parinirvana, or the final deathless state, and abandon his earthly body. After this, the Buddha ate his last meal, which he had received as an offering from a blacksmith named Cunda. This caused him to become violently ill and die.
