The source of things, O descendant of Bharata! is unperceived; their middle state is perceived; and their end again is unperceived. What (occasion is there for any) lamentation regarding them? One looks upon it as a wonder; another similarly speaks of it as a wonder; another too hears of it as a wonder; and even after having heard of it, no one does really know it. This embodied (self), O descendant of Bharata! within every one's body is ever indestructible. Therefore you ought not to grieve for any being.
