Terma

"Guru Padmasambhava hid hundreds of teachings and instructions as treasures, in the forms of scriptures, images, and ritual articles, to be revealed at an appropriate time in the future. He saw that though the time was not ripe for him to teach them at that time, many of the teachings would benefit future generations. Since that time, more than one hundred tantric masters have revealed these treasures and taught them, as instructed by Padmasambhava, to their students. In this way, the Terma (revelation) lineage emerged." (from http://www.kagyuoffice.org/buddhism.nyingma.html)

Examples of terma in the Shambhala Lineage are the Sadhana of Mahamudra and the Shambhala Teachings. Chogyam Trungpa Rinpoche was one of the 20th century's great tertons (treasure revealers), and discovered many dozens of terma from age six until his death. Most of these disappeared during the invasion of Tibet, but many are now being found and taught by his nephew Karma Senge Rinpoche.
