Mahayana Buddhism diverged into numerous schools over 2000 years and advanced concepts like Buddha having multiple manifestations and being a celestial being rather than human. It emphasizes bodhisattvas who pursue enlightenment to help all beings. Major schools include Madhyamika focusing on truth beyond duality and Yogachara denying perceivable truth exists. Other influential schools are Pure Land focusing on Amitabha Buddha, Zen emphasizing intuitive meditation, and Tibetan Buddhism incorporating local Bon beliefs and tantric practices.
