What are some of the ideologies of Mahayana Buddhism?

Mahayana Buddhism saw the emergence of the idea of Bodhisattvas. Bodhisattas were deeply compassionate people who accumulated knowledge through their consistent efforts. The Bodhisattas did not attain Nibbana after achieving the knowledge but instead they helped the common people to solve their problems. In the Mahayana tradition, the concept of the worship of the images of Buddha and Bodhisattas became a common practice. The followers of this new tradition of Buddhism depicted the old tradition of Buddhism as Hinayana Buddhism.
