Strange that a non-religion should be concerned about what it says in some scriptures. But the worst part of that, is that it isn't even true. Just as the heralds of Rawatism completely distort the western Bible, so do they the same to Hinduism. The Bhagavadgita is, amongst other things, a lecture on ethics. I'm pretty sure that the phrase "they are already dead" doesn't even exist. The meaning of the part where death is discussed, the second chapter, has been very distorted to create such an interpretation.
