Enlightenment — Everyone can be a Buddha?
Siddhartha gave up his life as a prince to find an answer to why people have to suffer and die. He probably thought about questions like “Why are we born? Why do we have to grow old and die? What is the purpose my life?” To make a long story short, he eventually learned to meditate. Through very deep meditation, he finally achieved “full-awakening” or enlightenment — a state when one understands how everything exactly works and interrelates in the universe, or a demonstration of non-exclusive omniscience. He became the Buddha.
According to the Buddha, people are trapped in these endless cycles of birth, death and rebirth. At the same time, everyone possesses the precondition to attain enlightenment to escape this trap and become a Buddha.
