Yes, in my opinion every culture talks about the immortal life in one or other way but truly we don't know how it is or how it will be, where it is and where we will get it, we get in this life or after life. It's an mystery until we experience the immortal life.
Many believe that we have after life and if we go through from the history or browse some videos then in my opinion i don't know it's true or not but some say that people saw after life in Near Death Situations.
And in my opinion in past many people searched for some places or for some water which is said to be the way for immortal but in my opinion no one reached to the stage or place of immortal.
And we cannot look into past to see the truth of immortality because in current times we are only experiencing the phase of perish and not immortality. Let's see if we could find any practicality in future.
Wishing you an great day and stay blessed. 🙂
