A selection of texts on the theme of prophecy or predictions (Skt. vyākaraṇa; Tib. lung bstan):
This revealed treasure text (gter ma), included in the Könchok Chidü (dkon mchog spyi 'dus), contains prophecies about future degenerate times and is purportedly the first guidebook to the hidden land of Pemakö (here spelt Pemokö).
In this famous history of the sacred stūpa of Boudha, Guru Padmasambhava recounts the stūpa's origins. In response to a request from King Trisong Deutsen, he tells how a humble poultry-woman first extracted a promise from the king and then built the stūpa together with her four sons, who were all later reborn as prominent figures in the introduction of Buddhism to Tibet. Padmasambhava also describes the benefits to be gained from circumambulating the stūpa and making offerings before it, and concludes with a series of prophecies concerning the stūpa's restoration.
Words of the Buddha
Jamyang Khyentse compiled this prophecy from the words of the Buddha. Before an audience that includes Ānanda and the future Buddha Maitreya, the Buddha tells how this text will appear from a meteorite and be disseminated by Avalokiteśvara. He also describes how a series of terrible events, including widespread disease, famine and warfare, will occur during the degenerate age, unless this text can be widely copied and recited as an antidote to such ills.
