Why is death a loss?

The days feel like years Awaiting salvage of my pieces I will go in a moment But, have to live for years Life is a constraint Imprisoned or liberated But, the cage is a reality For, every illusion is a reality It continues after it ends Though, not perceptible We don’t see all Much is outside our range Smallest to the biggest Life and death is not visible It is only an impression Parting day too is an illusion I may continue in some form Not perceptible to others But I love my perceptible form So, death is a loss to me
