Tertön (Tibetan: གཏེར་སྟོན་, Wylie: gter ston ) is a term within Tibetan Buddhism. It means a person who is a discoverer of ancient hidden texts or terma. Many tertöns are considered to be incarnations of the twenty five main disciples of Padmasambhava. A vast system of transmission lineages developed. Nyingma scriptures were updated by terma discoveries, and terma teachings have guided many Buddhist and Bon practitioners.
According to generally accepted history, the rediscovering of terma began with the first tertön, Sangye Lama (1000–1080). Tertöns of outstanding importance were Guru Chowang (1212–1270), Rigdzin Gödem (1307–1408), Dorje Lingpa (1346–1405), Ratna Lingpa (1403–1478), Pema Lingpa (1450–1521), Namchö Mingyur Dorje (1645–1667), and Jigme Lingpa (1729–1798), Jamyang Khyentse Wangpo (1820–1892) and Orgyen Chokgyur Lingpa (1829–1870).
Throughout the centuries many more people were known as tertön. Five of them were widely recognized as very important ones and called the "five tertön kings:"
Why don't you get a life and grow up
Why don't you realize that you're fucked up
Why criticize what you don't understand
Why change my words, you're so afraid
You think you have the right to put me down
Propaganda hides your scum
Face to face you don't have a word to say
You got in my way, now you'll have to pay
Don't, don't believe what you see
Don't, don't believe what you read
