In the Yungdrung Bön tradition, the place where the deities and objects of veneration are gathered is called the “Tsok Zhing”, the “Field of Accumulation”. It is also sometimes translated as the “Field of Merit” or the “Merit Field” because what is being accumulated by paying homage and making offerings to this place is merit, or virtue. This is the Merit Field according to the Menri Tradition from a drawing done by the great master and scholar HE Yongdzin Tenzin Namdak Rinpoche.
This is the lineage of monastic discipline. These lineage masters have all taken monk’s vows and therefore wear the appropriate clothing to distinguish them from laypeople.

Once inside the cave, he saw a figure that resembled a monk but whose hair had grown down to the ground and become entangled. The karmic connection immediately ripened and he joyfully began prostrating and requesting that the monk awake from his meditation. Day after day, he returned to the cave. First, one of the monk’s eyebrows moved, then a portion of his face. On the third day, he yelled at the slave, “Are you a human or non-human obstacle?” The slave replied that he desired to become his disciple. The monk agreed and gave him full ordination.

In the Yungdrung Bön tradition, the place where the deities and objects of veneration are gathered is called the “Tsok Zhing”, the “Field of Accumulation”. It is also sometimes translated as the “Field of Merit” or the “Merit Field” because what is being accumulated by paying homage and making offerings to this place is merit, or virtue. This is the Merit Field according to the Menri Tradition from a drawing done by the great master and scholar HE Yongdzin Tenzin Namdak Rinpoche.
The Lineage of the Profound Guidance through AH, also known as the AH Tri, is one of three lineages of Dzogchen teachings in the Yungdrung Bön tradition. (See previous posts regarding The Aural Transmission of Zhang Zhung and the Renowned Three Cycles of Dzogchen.) This lineage of Dzogchen teachings was closely associated with the Dru family. From Menri Abbot Nyammé Sherap Gyaltsen until Menri Abbot Kunzang Gyaltsen, the lineage was passed down through the abbots of Menri Monastery.
1. Founder of the lineage, Me’u Gongdzö Ritropa. He is often referred to simply as Dampa, “The Sage” or “The Saint”. (See previous post, The Saint.) He exhibited many signs of accomplishment such as flying through the sky and leaving his hand and foot prints in stone. Although his primary focus was upon his meditation, he also wrote a number of texts. In addition to material he collected from other sources, he added his own gong ter, or mind treasure, to this collection. He organized the practice of the A Tri into 80 meditation sessions.

2. Gomchen Barwa. He was an unconventional person and became a great yogi. He was known for odd and somewhat dramatic displays. One day, Gongdzo Ritropa took Gomchen to a grassy area that was quite wet. The lama knew that Gomchen was known to have been quite athletic in his youth. So he told him to make a great leap. In doing so, Gomchen slipped and violently fell down. In that very instant, he achieved spiritual realization without interruption. Rather than taking ordination, he remained a laymen his entire life. He had many disciples and attained the rainbow body of light.
3. Kyunggom Joyung.
4. Dampa Tsulshé.

10. Dru Namkha Odzer.He was the younger brother of Dru Gyalwa Yungdrung.

Tapihritsa, He was born into a nomadic family in the country of Zhang Zhung. He practiced at a place near Mt. Tise known as Sengé Tap. He practiced for nine years without interrupting it with ordinary, human speech. He achieved the rainbow body of light. After this, Tapihritsa manifested as a young boy and began working as a shepherd for a wealthy man in the area where Nangzher Lopo was practicing. Upon meeting, Nangzher Lopo asked the boy a series of questions and became annoyed at his answers. Challenging him to debate in front of the Zhang Zhung king, the boy laughed and began speaking about the true nature of mind. Realizing that this was an emanation and not an ordinary boy, Nangzher Lopo fainted. Regaining consciousness, he saw that the boy had transformed and was showing a clear and luminous body surrounded by a rainbow and suspended in space.
Gyerpung Nangzher Lopo, He extensively practiced the cycles of Zhang Zhung Meri and Gekho. In doing so, he acquired great magical power. He was the priest for the Zhang Zhung king and was well-known throughout the kingdom. Because of his devotion, he met and received teachings from Tapihritsa 3 times. He lived for 573 years.

He lived for 1,600 years and his body showed no signs of aging. He then transformed himself into a turquoise cuckoo and flew off towards the southwest in order to subdue demons.
Here, the lineage splits into Upper & Lower systems of transmission according to the geographical location in which it was transmitted.
The Upper System of Transmission
The Six Realized Sages
To these disciples was transmitted the Four Cycles of the Precepts Transmission (the Ka Gyü Kor Zhi), but not the Experiential Transmission (the Nyam Gyü).
Gugé Loden, He received the teachings from Pöngyal Tsenpo in an area near Mount Tisé. As a youth, he worked as a goatherd and had often dreamt of a blue cuckoo speaking to him. One day, he watched as a cuckoo descended from the sky near him. Going closer, instead of a bird, he found a yogi in a blue robe. This was Pöngyal Tsenpo.
Pureng Kunga, He practiced in the area of Mount Tisé. By following his lama’s guidance on Dzogchen, he attained realization in one month.
Naljor Sechok, He had the power to prolong his life span and displayed many miracles.
Kyungji Mutur, He was a wandering yogi without any particular place of practice.
Dewa Ringmo
Tokmé Zhikpo, He lived most of his life in a cave. He gave the full transmission to Yangtön Sherap Gyaltsen. This same lama also received the full transmission of the Lower system of transmission. In this way, he reunited the two transmissions.
The Lower System of Transmission
Lhundrup Mutur
Shengyal Lhatse, He lived for 113 years.
Lhagom Karpo, He lived for 97 years.
Ngodrup Gyaltsen, He was the son of Lhagom Karpo. He asked his father for teachings but his father refused and told him that he had performed a divination that indicated that his son was not a good candidate. Ngodrup then abandoned his wife and child and went to study with a Buddhist. Soon after this, his father reconsidered his decision and agreed to teach him. He lived for 73 years.
Orgom Kündul, Few Bönpo followers sought teachings from him but many Buddhist practitioners sought him out. He lived for 80 years.
The Upper and Lower Systems of Transmission reunite in the person of Yangtön Sherap Gyaltsen
Yangtön Sherap Gyaltsen, He was born into the prestigious Yangtön lineage of Dolpo, Nepal. He lived and taught during the 11th century. He received the full transmissions of both the Upper and the Lower Systems of Transmission and therefore united the transmissions. Out of compassion, he wrote down some of the teachings as well as commentaries. According to prophecy, his life span was to be 75 years but due to writing down the secret teachings, he died at the age of 63.
Here, the lineage splits again into the Southern and the Northern Lineage. Below is the list of the lamas of the southern Lineage of Transmission.
The Five Masters of the Mantra and the Mind:
These five masters held the transmission of both the precepts as well as the practice of the yidam and protector Zhang Zhung Meri
Dampa Bumjé, He spread the Bön teachings in the areas of Dolpo, Mustang and Western Tibet. His father was Yangtön Sherap Gyaltsen. After his death, Dampa received teachings from his mother. Because of his extraordinary meditative experiences, he added his own teachings to those of his father in the Experiential Transmission.
Lu Drakpa Tashi Gyaltsen, He was also a son to Yangtön Sherap Gyaltsen. Unlike his brother, he was a wandering yogi. He lived for 85 years.
Tokden Wonpo Yeshe Gyaltsen, His mother was Yangtön Sherap Gyaltsen’s daughter. His father was a bandit and he joined him in his exploits. One day, he father was killed during a fight and he was badly wounded. Once he recovered, he began to seek revenge. After some time had passed, he became tired with fighting and went to his uncle, Dampa Bumjé, to learn to read so that he could read the scriptures. However, his progress was slow and he went to his other uncle, Lu Drakpa, and asked for teachings that didn’t require the ability to read. Having received the teachings of the Zhang Zhung Nyen Gyü, he practiced and attained realization.
Yangtön Gyaltsen Rinchen, From the age of 8 until 21, he practiced tantra. At the age of 21, he received the Dzogchen teachings. He founded the monastery of Samling in Dolpo, Nepal.
