Juliana, Sakha republic (Yakutia),  Юлиана, Республика Саха. (Якутия, Россия)  This clip is an ancient hymn dedicated to the Great God of the Sky - "Tengri"

 Tengri (Proto-Turkic *teŋri / *taŋrɨ; Mongolian script: ᠲᠨᠭᠷᠢ, Tngri; Modern Mongolian: Тэнгэр, Tenger;  Modern Turkish: Tanrı), is one of the names for the primary chief sky deity in the religion of the early Turkic (Xiongnu, Hunnic, Bulgar) and Mongolic (Xianbei) peoples.

Worship of Tengri is sometimes referred to as Tengrism. The core beings in Tengrism are Sky-Father (Tengri/Tenger Etseg) and Mother Earth (Eje/Gazar Eej). It involved shamanism, animism, totemism and ancestor worship. Historically, it was the mainstream religion of the Turks, Mongols, Hungarians and Bulgars. It was the state religion of the ancient Turkic states like Göktürks Khaganate, Avar Khaganate, Western Turkic Khaganate, Great Bulgaria, Bulgarian Empire and Eastern Tourkia.

As a modern revival, Tengrism has been advocated among intellectual circles of the Turkic nations of Central Asia, including Tatarstan, Buryatia, Kyrgyzstan and Kazakhstan, in the years following the dissolution of the Soviet Union. It is still actively practiced and undergoing an organised revival in Yakutia, Khakassia, Tuva, Buryatia and other Turkic nations within Russia. Burkhanism is a movement kindred to Tengrism concentrated in Altay.

Khukh and Tengri literally mean "blue" and "sky" in Mongolian and modern Mongolians still pray to "Munkh Khukh Tengri" ("Eternal Blue Sky"). Therefore Mongolia is sometimes poetically referred to by Mongolians as the "Land of Eternal Blue Sky" ("Munkh Khukh Tengriin Oron" in Mongolian). In modern Turkey Tengriism is also known as the Göktanrı dini, "Sky God religion",Turkish "Gök" (sky) and "Tanrı" (God) corresponding to the Mongolian khukh (blue) and Tengri (sky), respectively.
