That is a very powerful song, and well-suited to a funeral or any such sacred occasion.

You can't go wrong with that sort of thing. If there is, in fact, nothing out there...no God...no afterlife...such songs still summon up powerful and meaningful feelings in people and serve a good purpose. If, on the other hand, there is something out there, and there is an afterlife, then such songs give respect and assistance to it.

Only the hardened heart of the cynic or the overly proud intellect of someone who is on a personal vendetta against all such beliefs for his own ego's satisfaction can have the ill will to constantly aggressively attack all such practices simply as a matter of course...just because they are not practices of the attacker's own personal choice.

For my own part, I am certain that there is some higher intelligence involved intimately within and behind everything we experience in this life. I don't care what people call it or what name they give to it. I don't care what religion they clothe it in or if they attach no religion at all to it. It doesn't matter. I believe it is here, always has been, and always shall be, and we are all part of it in some way. Science is a useful way of observing its effects in this world. Religious practices are a symbolic way of giving it respect and honoring it. Ultimately, it's the force of love.
