Santarakshita was responsible for establishing the first Buddhist monastery in Tibet, known as Samye Monastery. He also introduced the Indian Buddhist philosophical tradition to Tibet.

Buddhism became the dominant religion in Tibet and remains so to this day. The teachings and practices of Buddhism also influenced Tibetan art, literature, and philosophy, creating a unique blend of Indian and Tibetan traditions.
