LifeGem / Ashes, Diamonds, and the Metaphysics of Presence

Is the body really an earthly “tent,” as the Christian scriptures declare, a vessel, which without the spirit is only a corpse? Is a dead body destined to return to the earth, to become mineralized there, broken down into the elements from which it was made?
