Baiktse Deity is also known as Tricpa Chamsin. One is one of the main protectors of the Sakyapa school, he is also a Dharma protector of the Gelugpa school as well. He is also known as a father of Noo-jin Tseu Marpo. Here is a history of Baiktse Deity according to the Sakya Lama Tsarchen Losel Gyatso. Many kalpas ago two sons were born in the family of king Sergyi Shugchan and queen Upale Ke. The older brother's name was Trakden and the younger brother's name was Trakgye. They had different religious belifs and they could not agree with each other. They had many debates. In these debates whoever lost had to follow the winner's religion. The older brother won but the younger one refused to follow him and ran away. The older brother caught him and tried to punish him, but the younger brother said: "Even if you will try to kill me I will not accept your religion, please let me go and I promise in the future when you will reach Enlightenment, I will protect your teachings". The older brother released him and gave him a set of copper armour, a coral stick, an arrow and a bow; and he gave him the name Sogtag Yamshi Marpo. Then they split. In another lifetime when the older brother became Buddha (Shakyamuni), the younger brother was born in the North West Marutzi cemetery. His father's name was Nujin Zangkiralpachen and his mother's name was Sinmo Thrakiralbachin. The parents laid two eggs, one of them was coral, another one was "se" (name of material). Those eggs flew in the sky, conquering many gods, then they flew into the earth, conquering many nagas. They even threatened their own parents. The parents asked Akachati, Mahakala's mother, for protection and Akachati threw her katamka ( a ritual stick) at the eggs and broke them. From the coral egg a coral man with yellow hair binded on the top of his head came out. He was wearing copper armour, carring a copper sword, an arrow and a bow and a coral stick. He said:" My name is Sogtag Yamshu Marpo". From another egg the blue female came out. She had shell teeth and turquoise eyebrows, her hair was made out of fire. She was wearing an agate and lapis lazuli necklace. She was carrying a copper knife and a phurba and she was riding a maneating bear. Akachati subdued them. Thus they became the Dharma Protectors. The lineage of this Deity was carried by Marpa Losawa and Ne Lotsawa. Ne Lotsawa gave it to Nakaupa. Nakaupa gave it to Sachen Kunga Nyingpo. Thus Baiktse Chamsin ( brother and sister) became protectors of the Sakyapa.

BAIKTSE CHEN, (English: the Great Coat of Mail, Sanskrit name: Prana Atma), the main protector for the Hayagriva cycle of practice.

With one face and two hands, in the appearance of a red 'tsen' daemon, dressed like a Tibetan warrior, he is covered in protective armour. In the right hand he holds a sword with a black scorpion shaped handle. The left hand clutches to the breast a fresh heart with a bow and arrow held in the bend of the elbow and a long lance and banner leaning against the shoulder. Aside from the armour, he wears all the usual wrathful vestments such as the crown of five skulls, a necklace of fifty freshly severed heads, and the like. Standing atop a sun disc with the right foot on the corpse of a horse and the left on the corpse of a man he is completely surrounded by the flames of pristine awareness.

At the top center is the Buddha of Medicine, blue in colour, with the right hand holding the stem of a medicinal plant. The left is placed in the lap holding a begging bowl filled with healing nectar. At the left is the Indian mahasiddha Saraha holding upraised an arrow shaft. At the right a lama wears monastic robes and a yellow cap. With the right hand placed at the heart he holds the stem of a lotus blossom supporting a sword and book. The left hand placed in the lap holds a gold vase.

To the right of the central lotus seat is the consort, Goddess of Life, with a red face and blue body. In the right hand she holds aloft a sword and in the left she stabs with a 'phurba' (Skt.: kila, Eng.: peg) dagger. As a mount she rides a bear clutching a small human corpse in the jaws. To the left of the lotus is the son, Lord of Life, red in colour with one face and two hands, dressed in similar attire as the father. He holds a lasso in the right hand and a spear in the left, riding a wolf.

Surrounding the central figure is a retinue of 29 butcher daemons, red in colour, with one face and two hands holding various instruments and engaged in the work of carving the flesh from corpses. At the bottom center, placed on tiger skin mats, are three skullcups with nectar on the left, blood on the right and a wrathful triangular torma (Skt.: balim. Eng.: stylized food) offering in the middle.

The background is devoid of scenery save for a rocky, jagged, windswept land locked in perpetual twilight. Within the Sarma Schools the practice of Baiktse Chen was popularized by Marpa Lotsawa and Sachen Kunga Nyingpo, the respective founders of Kagyu and Sakya.

Lineage from India: Vajradhara, Mahadeva, Nyi Od Drakpa, Dawa Nagpo, Shridhara Krashu, Nyen Lotsawa Dharma Drag, Kha'u Chokyi Gyaltsen, Sachen Kunga Nyingpo (1092-1158), etc.
