Tengri is the same as Jehovah; they are just different names for the same God. Shamans, like Christians, serve Him. In many other religions, people have called the same one God by different names. There is an ongoing debate about these names, which is pointless. It doesn’t matter what name – Allah, Jehovah, Tengri, Zervan, and so on; it’s time to unite all religions instead of fighting against each other.
