The ancient Turks believed that there were some latent forces in the nature: mountains, hills, rocks, valleys, rivers, water springs, trees, forests, seas, iron, swords, etc. All these materials were separate souls at the same time. Furthermore, the gods such as the sun, the moon, starts, lightning, thunder, lightning flash, etc. were imagined. The spirits were divided into two groups such as good-evil spirits, in other words the spirits that brought goodness or evil. Besides the male gods, there was a goddess called as "Umay". This consideration about the natural events and incidents that were observed in the physical environment was general in all of the ancient tribes including the ancient Greece and Roma. Furthermore, these spirits and gods had significance in various degrees in accordance with their influence over the lifestyle.
In spring (in the month of May) and in autumn, the Asian Huns would sacrifice animals for their ancestors and the natural gods within the region of Lung-çu region. The ruler tan-hu had also believed in the sun in the daytime and in the full moon at night. The Huns, Gokturk and Uighur Turks would estimate and control the appropriateness of their activities in accordance with the movements of the moon and the stars. Tabgaç people would also sacrifice animals for their ancestors in the spring and autumn. Pursuant to the sacrifice of an animal within the "stone-house" that was considered as the temple, the beech trees would be planted in the surrounding. Therefore, these trees would constitute the divine forests. Gokturk people would present their sacrifices to their gods in front of the cove of wolf-ancestor.
In the European Huns, the sword of the war god that had been lost for a long time were found and submitted to Attila. Therefore, this was considered as the symbol of the world domination of the Hun ruler. In case of deaths, mourning ceremonies would be organised, and the people would ride horses at a gallop around the tent of the dead person, and they would tear their hairs. Furthermore, they would scratch their faces and ears with a knife and shed blood. Furthermore, feasts would be organised. These ceremonies were called as "yoğ".
According to the records within the Byzantine resources, the Turks had also believed in the fire. However, this belief in fire was only observed in the period of the Gokturk state and actually in the Western Gokturk section. Therefore, it has been understood that this belief resulted from the influence of Iranian Mazdaism (Zoroastrianism) and it was not widespread among the Turks.
The natural spirits were called as Yer-su "Yir-sub" (Ground-water) in the period of the Gokturk State as it has been understood from the inscriptions. This term was also used by the Uighur people in the form of "yer-suv". Yer-su spirits were considered as the holy "iduk". Only the names of two yer-su spirits were cited within the inscriptions. " "Idux Ötükan" and "Tamıg ıduq baş". As it has been known, the first spirit is the source of the "khanate" (It must not have had any relation with Atügan that was the Mongolian earth god. Actually, there was not any earth god among the Turks. However, the region could have been considered in this way in the period of the Mongolians). The latter spirit was the spiring of the holy Tamig (Tamir stream). Since all of the yer-su spirits were imagined as spiritual powers rather than material forces in the actual Turkish culture, there were not any mythologies that were rumoured about these spirits.
