Gampopa, also known as Dakpo Lharje, was a Tibetan Buddhist master who lived from 1079 to 1153. His full name was Gampopa Sonam Rinchen, with "Sonam" meaning "merit" and "Rinchen" meaning "precious jewel" in Tibetan.

Gampopa was born in a small village in central Tibet and was raised by his uncle after his parents' death. He received a traditional Buddhist education and was ordained as a monk at the age of 16. He studied under various masters and became well-versed in the teachings of the Kagyu lineage, one of the four main schools of Tibetan Buddhism.

Despite his extensive knowledge, Gampopa felt that he had not yet found a true understanding of the teachings. He then heard about Milarepa, a renowned Tibetan yogi, and decided to become his disciple. Under Milarepa's guidance, Gampopa underwent rigorous training and attained enlightenment within six years.

After Milarepa's passing, Gampopa continued to spread his teachings and founded the Dakpo Kagyu lineage, which combined the teachings of the Kagyu and Kadampa schools. He also wrote several influential texts, including "The Jewel Ornament of Liberation" and "The Precious Garland of the Supreme Path."

Gampopa's teachings emphasized the importance of integrating meditation and daily life, as well as the practice of compassion and wisdom. He also stressed the importance of a qualified teacher and the need for a strong foundation in the Buddhist teachings.

Gampopa's legacy continues to this day, with his teachings being passed down through the Dakpo Kagyu lineage. His influence can also be seen in the teachings of other Tibetan masters, such as the 14th Dalai Lama.

In conclusion, Gampopa's full name was Gampopa Sonam Rinchen, and he was a highly respected Tibetan Buddhist master who played a significant role in the development of Tibetan Buddhism. His teachings continue to inspire and guide practitioners on their spiritual journey towards enlightenment.
