Termas are Tibetan scriptures said to have been dictated by the great teacher Guru Rinpoche (known in the West as Padmasambhava) to his consort Yeshe Tsogyal and then hidden for discovery by later generations.


The above image shows the final page (with the colophon, giving its name, the Lama Norbu Gya Tso Khyil-kor Las Rim) of the terma discovered in 1483 (or, as it is written here, the Male Earth Monkey year) by Pema Lingpa, then subsequently lost for several hundred years before being found by Lama Mike in 1986.
