We die twice. first is the physical death where our body stops working,the second is when the last person that knows us and our name dies also.

There would be a time in the future where no one would know your name,nobody alive would have memories of you because everyone who had memories of you are also dead, and no one knows you ever existed… that is when you truly die.

Christian theology suggests that in order to elevate to a higher consciousness a person has to die and be born again In Christ, Hindu describes the same idea as Krishna consciousness, other people describe the process as mysticism.
Which ever way you perceive reality you’ll be dead permanently a few hours after your heart and brain stop functioning and anyone who promises you another life after death is a fraud and charlatan.
