In my humble opinion, I think Siddharta was a true seeker of knowledge for he left his palace, wife and son, at the age of 29, to find answers to the purpose of life and all the difficulties etc of life. He wandered for 7 years, living on the donations by common people of food and clothes when at the age of 36, he was satisfied with the answers he obtained via enlightenment. Thereupon, he decided to share his knowledge with other seekers and lay people, while travelling from place to place.
