If we maintain our physical form, is that the form we have at death, do we age or change further? Or is it our physical form at peak physical condition? Will it be warts and all?
If it is only the mental/spiritual, will we not be very different to our mental/spiritual side in real life that is so much influenced by the physical?
Perhaps we should strive in life to isolate that which is the spiritual/mental side from the physical side and its influences.
