Lama is a title for a teacher of the Dharma in Tibetan Buddhism.
The name is similar to the Sanskrit term guru, meaning "heavy one", endowed with qualities the student will eventually embody.
The Tibetan word "Lama" means "highest principle", and less literally "highest mother" or "highest parent" to show close relationship between teacher and student.
