9. We are immortal

There is well known principle that everything is mortal .

But the same scriptures also say that what appears to be happening, has happened earlier and will happen in future also. The world as seems in present has been same in the past and will remain in future also. Therefore we can say that we are immortal not only by substance or soul but by form also? Circle of birth and death is only a phenomenon of appearance and disappearance of form!
