The Dalai Lama, is the Tibetan Buddhist Political and Spiritual leader. His name is Tenzin Gyatso. Dalai Lama means "Ocean of Wisdom" (Lama meaning Guru or Wise leader....)he is specifically leader of Tibetan Buddhism, and is greatly respected by Buddhists everywhere, but he is not the Principal Lama of every Buddhist School.
he is a reincarnation of every lTibetan Lama of this tradition, before him, and is the 14th embodyment.
When the previous Lama died, Monks from this tradition began to look for his reincarnation (a 'Tulku') and eventually found him when he was aged around 2 years. The conditions and evaluations on recognising a reincarnated Lama are extremely complex and precise, and Tenzin Gyatso filled all the criteria.
Reincarnation of such a kind is very exact, whereas re-birth, also a Buddhist view or concept, is slightly different....
The Dalai Lama is also the Personification of Avalokitesvara, or Chenrezig (in Tibetan) the Holy Buddha of infinite and boundless universal Compassion.
Hope this helps.
