The Buddha was born a prince in Lumbini, India. His father, the king, knew he would become enlightened and not want to rule if he saw all the suffering outside of the palace, so he forbid him from leaving.
However, in his late 20s the Buddha left the palace and saw pain, death, and sickness. The Buddha was deeply upset and wanted to know how how to end all this suffering.
Pain and death are inevitable, but to suffer is a choice.
If you free yourself from desire and attachment, you will not suffer.
Outside, the Buddha also saw a monk who shaved his head, only wore a tattered robe, and gave up all his possessions so he could clear his mind and find the key to happiness. The Buddha decided to leave the palace and do the same in hopes of finding the cure to suffering.
Do not lie, steal, or cheat.
Do not harm other living beings.
You are one with the Earth and nature
Do not rely your happiness on external factors because they are not certain.
The Buddha left the palace for six years, where he met with many masters who taught him meditation. Eventually, he decided he would stay in meditation under a large tree until he became fully enlightened; six whole days and six whole nights.
One morning, on the first full moon of May, the Buddha reached enlightenment. Any confusion or negative feelings he had vanished, and he gained ultimate awareness. He wrote the four noble truths, the three universal truths, and the Eightfold Path.
For the next 45 years the Buddha traveled on foot around Northern India, speaking to all types of people and teaching them about what we now call Buddhism.
