What does the sino-mongolian translation of dalai mean in english?

ocean

Explanation:

The word dalai means ocean in Mongolian, while the word lama signifies guru, teacher or mentor in Tibetan. Thus, Dalai Lama is regarded as a teacher as deep as the ocean and it is an important lama in the Gelug school of Buddhism in Tibet, which was founded by Tsongkhapa. In that respect, the Dalai Lama is considered to be the rebirth of Avalokitesvara, who was the embodiment of compassion, as well as to put on hold his afterlife to contribute to society.
