5. Conclusion

Therefore, if we look into the numerous important military expeditions that King Srongtsan had undertaken, alongside the contributions he made in art, architecture, law as well as establishing an indigenous writing script and Buddhism, it is difficult to categorize all these achievements in the short span of a reign of 20 years. This fact is convincingly proved by the impossibility of his son Gungsrong's enthronement at age of 13 and death at age of 18, which makes Srongtsan, a father at age 7 [629 CE] or age at 14 [617 CE]. The period that lapsed between Lhathothori and Srongtsan also do not support this theory, either.

These findings propel us to explore the possibility of taking Lhathothori and Srongtsan's birth beyond 173 CE and 617 CE, to look at 408 CE for Lhathothori Nyantsan's birth, and 569 CE for Srongtsan's birth as proposed by Gos Lotsawa and other scholars. These two years are the most probable and fits well with convincing narrative in Tibet's history. The tables derived from these facts also lead to a more reasonable conclusion. But we see that most of King Srongtsan‘s exploits and accomplishments were achieved in advanced age. We do not find any major achievements when he was younger. This may be because of a deliberate manipulation of historical years all along to forcibly fit everything he achieved into 33 years, or we might have been sidetracked. Nepalese Princess Balsa Tritsun of King Amsuvarman was said to have arrived in Tibet in 634 CE. But the King Amsuvarman's reign was 576-621 CE, and he died in 623 CE^[1], ruling out that King Srongtsan could have negotiated with him for his daughter's hand then. This could have happened much before. Thonmi Sambhota's visit to India and some other expeditions could have taken place much before 629 CE.

Therefore, the fact that King Srongstan Gampo lived for 82 years with the Earth-Ox [569 CE] as his birth year, is in congruence with the writings of early Tibetan historians^[2]. The Earth-Ox [569 CE] and Fire-Ox [617 CE] years got us King Srongtsan's age as 82 and 33 respectively with a difference of 48 years. The error of Earth-Ox [629 CE] with Earth-Ox of [569 CE], as noted in the 'Gos lotsaba's work, Blue Annals, can be seen as the cause of sixty years difference found in the Tibetan historiography.
