Yav (Jav), Prav and Nav are three worlds in old Slavic religion.

Yav

Yav is the material world in which we are right now. Gods however are equally part of Yav. Yav is contained within Nav.

Nav

Nav is the immaterial world, the world of the dead. Stars, which are the souls of the dead, as well as Svarga and Irij , are parts of Nav. The belief in Nav remains to this day, though it is no longer clearly defined.

Prav

Prav is the law of Svarog that governs both Yav and Nav. Modern parallels to this concept are laws of physics, but there is one big difference. The law that says that a stone falls when dropped is not only a mere observable fact: it is rightful, good and just that stones fall to the ground when dropped. A somewhat similar belief today is anthropic principle, but it only states that laws of physics are useful .
