why life ends?

flower lives for an hour
butterfly lives for a day
like a dry leaf blown from tree
my papa vanished
when stream of river keeps flowing,never stops
why life ends?
eagles fly during day
star burst at night
like a burning candle melts to end
my papa disappeared
when earth on digging vertically,has no bottom
why life ends?
his death-bed was surrounded by mute attendees
his dead skin piece was cut,stuffed into pipe and smoked
like a volcano
my papa exploded
when air fills space,never empties
why life ends?
i should prepare from his cremating remains,a glowing ball
i should observe every thursday,burnt thursday festival
like a phoenix bird
my papa evaporated
when sky keeps expanding,has no border
why life ends?
