Seventeen Tantras

Known by various names,
· rgyud bcu bdun 17 Tantras
· rdzogs chen gyi rgyud bcu bdun 17 Dzogchen Tantras
· man ngag sde'i rgyud bcu bdun 17 Mannagde Tantras
· yang gsang 'od gsal gyi rgyud bcu bdun 17 Tantras of Innermost Luminosity
with bcu dun being '17' and rgyud meaning 'Tantra', these texts of the Mannagde (Esoteric Instructions) Class belong to the fourth of the Four Cycles of Nyingtig teachings of the Dzogchen tradition.

Often, as can be seen in items 1 and 13, the texts are known by various short and long forms of their Tibetan name, making identification rather difficult for someone not acquainted with the language. In addition, items 3 and 14 illustrate how Tibetan titles can be translated in various ways without any such translation being more accurate; and a comparison between items 1 and 12 shows how important it is to pay attention to the Tibetan terms as the translations almost appear as the same for both.

Very interesting in this connection is the history of the religious cult of the seven celestial bodies. It appears for the first time in the Shumer-Accadian civilization where the names of the Sun, the Moon and the five planets, known to the Ancient world, are always accompanied by the word DINGIR god, akin to the Elam word TANRU. The Sun is called Dingir-UTU (Sun God) by the Shumerians, the Moon is called Dingir-sin (Moon God), etc. From this very part of the world the cult of the celestial bodies spread radially to the East and the West among the ancient peoples Assyrians, Indo-Iranians, Hittites, Celts, Romans, etc. Widely spread are also words like DINGIR and TANRU or the like: the Assyrian word TANRA heavenly body, the Indian TARA star, the Hittite TARA heavenly light, the Celtic TARAN god of thunder, the Anglo-Saxon THUNDER, the Pamir word TANDRA lightening, and the remotest cognate the Turkic word TENGRI (god of the bright blue sky).
Old Bulgarian religion, with its devotion to the seven celestial bodies and the Supreme God, called Tangra and Edfu, is part of this religious system. What is more, it does not represent the most simplified Turkic variant but the initial well developed system. This is not primitive Asiatic shamanism, as interpreted by some authors, but one of the oldest religions of humanity. It is high time to acknowledge this fact.

It has been mentioned: "The Sammoha Tantra speaks of the Tantric culture of foreign countries like Bahlika, Kirata, Bhota, Cina, Mahacina, Parasika, Airaka, Kamboja, Huna, Yavana, Gandhara and Nepal".
