What is Death, what does it mean to die
Death is freedom to rebirth anew, Birth is imprisonment to suffer karmic dues. Praise to those who are set free, pray for those who remain forced to stay due to their karmic burden.
Our body is just like clothes for the soul, changed often and quite meaningless. During the time the soul wears that particular set of clothes it’s important, but given the amount of times it changes clothes, one set is not important. Each body experience is housed in the mind, the collector of knowledge and part of our spirit.
The mind does have some physical element since it’s still within the realm of causality. This consciousness then reviews the life it had and decides what is next, if it failed to complete its mission and because diseased (too negative) then it will put itself into a sort of hospital where the negativity can be removed. This place is often called hell. It is not permanent. If the review shows spiritual merit or success with its mission, more choices abound. Perhaps moving on to the next mission or staying in the lower heavens (astral realms) for a while.
If this is the case then the body used will be a dreamlike (not physical) version of the one that just died, during the time it was most beautiful. For example, if a 100-year-old woman dies and had earned merit during her life, she may end up in Heaven looking like she did at 20-years-old. But the form in Heaven is not real, just something to distinguish all the light-energy-bodies. Even a dead animal may look like a human or animal, the form is not important as it’s not real anyway.
