The earliest revelations of the Great Perfection are those said to have been disseminated in Tibet in the latter half of the eighth century, and which retroactively were classified as the Mind Series to distinguish them from later developments. They begin with a collection of quite short texts known as The Eighteen Texts of the Mind Series (Sems sde bco brgyad), and then subsequently proliferate into a large family of texts spawned by the original collection’s expansion, modification, and so forth, culminating in a series of texts centered on The All-Creating King (Kun byed rgyal po). Most of the resultant sub-divisions of the Mind Series rubric have names based upon geographical regions, clans, or individual founders. Padmasambhava (eighth century) does not figure prominently – if at all – in these early Great Perfection traditions; rather, Śrīsiṁha (eighth century), Dga’ rab rdo rje (seventh century?), and Vimalamitra (eighth-ninth century) are the main Indian figures cited as involved in their authorship, redaction, transmission, and translation.〔Germano, David (2005).
