This Lost Smile in the Dark Sky

Cleanse ourselves of sins
For death passes everyone
You'll never know when your day will come
But we'll all go one by one
It's all a mystery to me
Is there life after death ?
Or do we end up in a mortuary ?
After taking our last breath ?
Do our souls wander on earth ?
Or is it an end to vitality ?
Or is it a new birth...
To everlasting immortality ??
