Nav is a concept from Slavic mythology, which refers to the afterlife or the realm of the dead for the souls of the righteous. It is often portrayed as a place of eternal peace and happiness, where souls go after death to enjoy the rewards of a virtuous life.

In Slavic mythology, Nav is ruled by Rod, and is said to be a place of eternal peace and happiness for the souls of the righteous. The souls of the wicked, on the other hand, are believed to go to a place of eternal suffering and punishment, such as Peklo (the underworld).

Nav is often depicted as a place of light and warmth, where souls are rewarded for their virtues. The souls of the righteous are said to be surrounded by loved ones and enjoy eternal happiness, while the souls of the wicked are said to be punished in Peklo.

In some Slavic cultures, Nav is also considered a symbol of the hope for eternal life, and is associated with the idea that death is not the end, and that our actions in life have consequences that extend beyond the grave.
