Mary: They wake up in spirit, still alive, still with a body, albeit one different to what they were used to in their physical body, but still one in which they can touch and move around in - their spirit body, or spirit form.
And in our spirit bodies we don’t need to eat or drink, right?
No you don’t, your spirit bodies simply exist in the ‘Light’, that being the light that sustains all spirit life, and it’s also the same light that sustains your physical body only you’re mostly unaware of it. However should you feel you still want to eat and drink until you get used to your new way of living, you can. But it's all done with your mind with no physical substances moving into your spirit body. It's all something you pretend you are doing.
So there’s more to keeping our physical bodies alive then just eating and drinking the right things and treating it well.
