Marpa Lotsawa (mar pa) (1012–1097), sometimes known fully as Lhodak Marpa Choski Lodos or commonly as Marpa the Translator, was a Tibetan Buddhist teacher credited with the transmission of many Vajrayana teachings from India, including the teachings and lineages of Mahamudra.
Although some accounts relate that the Mahasiddha Naropa was the personal teacher of Marpa, other accounts suggest that Marpa held Naropa's lineage through intermediary disciples only. Either way, Marpa was a personal student of the Mahasiddha Maitripa.
Born as Marpa Chökyi Lodrö, in Lhodrak Chukhyer in the southern part of Tibet, to an affluent family, he began studying at a young age but was wild and untamed compared to other children. Marpa first received instruction for three years at Mangkhar with Drokmi Shakya Yeshe and mastered Sanskrit.
He decided to travel to India to study with renowned Indian Buddhist masters. Marpa returned home to Lhodrak and converted his entire inheritance into gold to fund his travel expenses and to make offerings to teachers.
Paindapa later accompanied Marpa to Pullahari, near Nalanda University, where Naropa taught. Marpa spent twelve years studying with Naropa and other great Indian gurus, most prominently Maitripada. After twelve years he set forth on his journey back to Tibet to teach and continue his Dharma activities.
Marpa was to travel to India twice more and Nepal three more times and studied with Naropa and other great teachers including Maitripa. On his third visit to India, Naropa, who was engaged in tantric practices, proved difficult to find.
Marpa now had received the full transmission, so Naropa formally declared Marpa to be his successor although he had other major disciples including Paindapa, Chitherpa, Shri Shantibhadra or Kukuripa, and Maitripa.
After Marpa's son Darma Dode Death Milarepa inherited his lineage in full. Marpa lived with his wife Dakmema and their sons in Lhodrak in the southern part of Tibet. Marpa is said to have founded Stongdey Monastery in Zanskar in 1052 CE.
From each of these teachers and students arose numerous lineages of teachings. Some of the lineages of teachings remained within schools and traditions named after the many students while other lineages were absorbed into the Sakya, Jonang or Gelug Traditions.
A school or tradition, such as the Kagyu School or Kagyu Tradition is a social and political construct. Schools and Traditions, two words often used interchangeably, are larger repositories for the hundreds of individual lines of teachings, i.e. Tibetan Lineages.
An example of a lineage in the Marpa Kagyu Tradition would be the Ganges River Mahamudra taught by Naropa to Marpa. Another would be the Chakrasamvara instructions taught by the Pamting Brothers of Nepal to Marpa.
