King Trisong Detsen
King Trisong Detsen (Tib. ཁྲི་སྲོང་ལྡེ་བཙན་, Wyl. khri srong lde btsan) or Trisong Deutsen [Déu tsen] (ཁྲི་སྲོང་ལྡེའུ་བཙན་, Wyl. khri srong lde'u btsan) (742-c.800/755-797 according to the Chinese sources) – the thirty-eighth king of Tibet, son of King Me Aktsom, second of the three great religious kings and one of the main disciples of Guru Rinpoche. It was due to his efforts that the great masters Shantarakshita and Guru Padmasambhava came from India and established Buddhism firmly in Tibet.

The Sons of Trisong Detsen
There is some confusion in the various histories regarding the number and the names of Trisong Detsen's sons.
According to Erik Haarh, he had four sons:
- Mutri Tsenpo (མུ་ཁྲི་བཙན་པོ་, mu khri btsan po),
- Mune Tsenpo (མུ་ནེ་བཙན་པོ་, mu ne btsan po),
- Muruk Tsenpo (མུ་རུག་བཙན་པོ, mu rug btsan po) and
- Mutik Tsenpo (མུ་ཏིག་བཙན་པོ, mu tig btsan po) who became known as Tridé Songtsen (ཁྲི་ལྡེ་སྲོང་བཙན་, khri lde srong btsan) or Senalek (སད་ན་ལེགས, sad na legs).
The situation is made more complex because later Tibetan sources use several of these names interchangeably. 
In Ancient Tibet , it says that there were three sons:
- Mune Tsenpo,
- Desong (ལྡེ་སྲོང་, lde srong) aka Senalek, and
- the third son, who is called both Murug and Mutik.
According to Dudjom Rinpoche's History of the Dharma (བདུད་འཇོམས་ཆོས་འཇུང་, Wyl. bdud 'joms chos 'jung), King Trisong Detsen had three sons:
- the eldest was named Mune Tsepo,
- the middle one Murup Tsepo, and
- the youngest Mutik Tsepo, or Senalek Jingyön.
The Daughter of Trisong Detsen
- Princess Pema Sel first died at the age of eight, but was brought back to life by Guru Rinpoche, and entrusted with the complete Khandro Nyingtik cycle by Guru Rinpoche. She was later reborn as the tertön Pema Lédrel Tsal, who revealed this terma cycle of teachings.
