Buddhism is not what buddha wanted. He might not even have any idea what buddhism means. He was against idol worship or all sorts of things. But buddhism does have those. Buddha probably created Sangha, not as organized religion, but as the mass of people with common interest who can be in discipline and can help each other and the society. But being limited to all these, even to the meditational technique, will never lead to enlightenment. Mastery of some meditational technique doesn't mean that he has been enlightenment. He has passed one stage, and for some that stage might not even be necessary.
