Siddartha Gautama was born in 560 in Nepal to Queen Maya and King Suddhodana.
A wise man named Asita said...
Your son is going to become a Buddha. He will reveal new knowledge as 'The Enlightened One.'
When Siddartha left the palace he saw four people ; an old man, a diseased man, a wandering holy man and a corpse being taken for cremation.
The sight disturbed him because he had never encountered human suffering before. he had always been protected from it and never knew it existed.
Siddartha spent time with five holy men. They lived a very hard life eating and drinking as little as possible.
To me, this way of life does not satisfy what it means to live. I will leave them and find the true meaning.
He travelled to Urevela and sat under a Bodhi tree where he meditated for 46 days.
Aha! I have it now! The enlightened way of life is to be neither rich or poor. Happiness doesn't come from having everything nor does it come from hardship and starvation. The right path is in the middle.
From that moment on he became known as 'the Buddha'.
