The body disappears when it is recognized as an illusion, there is no need to die
In "Absence from Felicity," Ken Wapnick includes a special message from Jesus to Helen about the resurrection. It came because Helen asked Ken if he believed in the physical resurrection of Jesus. Ken suggested she, "ask the 'Boss' himself." Here is most of the message:
My body disappeared because I had no illusion about it.. It merely became what it always was. And that is what 'rolling the stone away means.' The body disappears, and no longer hides what lies beyond... To roll the stone away is to see beyond the tomb, beyond death, and to understand the body's nothingness. I did assume a human form with human attributes afterwards, to speak to those who were to prove the body's worthlessness to the world. This has been much misunderstood. I came to tell them that death is an illusion, and the mind that made the body can make another since form itself is an illusion. They did not understand."
Leave it behind. It cannot enter Heaven. But I can take you there any time you choose. Together we can watch the world disappear and its symbol vanish as it does. And then-and then-I cannot speak of that. A body cannot stay without illusions, and the last one to be overcome is death. This is the message of the crucifixion: there is no order of difficulty in miracles. This is the message of the resurrection. Illusion are illusions. Truth is true. Illusions vanish. Only truth remains. [See "Absence from Felicity," 398-400.]
