BTW, I didn't like Siddharta at all. It's too mixed up with Hindu thoughts for me.
IMHO.
First off Hinduism is a relativly new word for many different people practising Vedic teachings.
Buddha was born into a Vedic system of thought. He neither denied the existance of or proclaimed the existance of God the creator.
There are so many scriptures written in His name hundreds of years after His death.
Some of His main teachings we know for sure are the following:
Do not follow the person follow the teaching.
Do not look towards Me ,or any other god or demon to help you.
He left us a strong wish for beings to listen to the teachings of Karma and the cause and effect of our actions.
He was born a prince and asked His followers to not take authority at face value and ALWAYS question authority.
He only left one mantra, that being The Hundred Sylabill Vajrasatva mantra. A mantra of purification .

There is a belief that He was A Buddha long ,long ago before being born historically on earth. Hence , His entire life is one of a 3 act play to teach sentients.
