The Dalai Lama is the spiritual and political leader of Tibet. Tibetan Buddhists have a system of recognizing lamas who have been reincarnated, such as the Dalai Lama. These are called Tulkus or Rimpoches, and they are recognized as having spiritual acumen. Lamas are recognized as having the spiritual authority to teach others. Monks can be lamas and/or rimpoches, and they enjoy respect and authority from lay people.

The fourteenth Dalai Lama is the reincarnation of the Bodhisattva of Compassion and presently leader of one branch of Tibetan Buddhism. Specifically "The Way of Virtue" (Gelugpa).

His position is traditionally the head of state of Tibet although he has been both head of state and head of Tibetan Buddhism while the reincarnation of the Panchen Lama is being sought. He has been in exile since 1959 in India due to harsh tensions with China.
He is the spiritual head and political leader of the Tibetan people. He seeks religious freedom in Tibet, and seeks an autonomous political position for Tibet in China. He has been very outspoken about human rights.
