Who Was the Buddha?

For many centuries it has been baffling for the scholars, especially for those holding a theistic view, that how could a person like Gautama Buddha deliver pearls of wisdom without being enlightened by the Almighty God.

It would be good to know the answers to these questions as that would help us to get the true picture of one of the greatest personalities of all time. Let's find out the truth behind the Buddha's wisdom.
