As mentioned above, recitation of the Tsédo a specified number of times has historically been—and is still nowadays—prescribed as a practice to people in poor health or facing other difficulties, and to practitioners more generally in order to ensure longevity, and so on. Recitation by the monks or nuns in a monastery is also commissioned for the same reasons. According to the Padma Kathang, the eighth century Tibetan king, Trisong Detsen, was advised to recite this text³⁷ daily (along with the other works known as the “ten royal sūtras”), as a result of which the king’s life is said to have been prolonged by thirteen years beyond the limit predicted by astrological reckoning.
