Elora: How does this shortening of our lifespan affect our experience of life and death?
Heru: The Human body is originally designed for a life span of 300-500 years. Because the lives of Humans are so much shorter, there is a fierce clinging to the body due to the feeling that one's life is not complete. Therefore whether a, person is facing mortality at 50 or 70 or 100, there is still a built in sense that they haven't completed a full cycle. Since this trauma has been repeated throughout many lifetimes, that fierce clinging to the body is also imbedded on a cellular level. Were Humans having the full span of years that they were meant to have, it would be easier for them to let go of their bodies at any time. The fact that they're not having a complete life span means that they are furiously trying to cling to the body and make it survive in an effort to complete the full cycle.
Just as the Hebrew tradition talks about the five phases of life, in truth there are really stages that go out to 500 years, which have not even been touched on or explored. These are natural states of evolution that would happen in one single lifetime, culminating in a state of deep mysticism. Therefore Human Beings have been continually robbed of the fullness of their life cycles.
