“Strela” ("The Arrow") is a calendar rite of the Eastern Slavs. It is an appeal to the god Perun. This ceremony is still being held in the villages of Bryansk (Russia), Gomel (Belarus), Chernihiv (Ukraine) regions. This territory is called "Borderland", "Three Sisters", “Origins”.
Many believe that three peoples and three states appeared from there. But there is only one evidence of this fact - the singing tradition.
