Question: Can life still be meaningful even if you were immortal?
Answer: “Meaning of life” is not connected to our physical existence, to this corporeal life. Thus mortality, immortality has nothing to do with it.
On the other hand our “fear of death” acts as a constant reminder, alarm clock to awaken questions, desires, a need towards finding our true meaning of life.
By finding this meaning, fulfilling our Human purpose in existence we can rise to a higher, “immortal” consciousness, perception of reality that becomes independent of our “mortal”, subjective limitations of time, space, physical motion.
