Nothing disappears without a trace.
~ Wernher von Braun
I am convinced that two things are immortal: love and consciousness. My love lives on in all the people I have loved and who have loved me. Think about a moment in your life when you felt loved or loving, and you will feel the change in your body. The love is still with you from that original experience.
Our consciousness, I believe, continues to exist without our body; it simply is. It is as difficult to describe why I know this to be true as it is to describe God. There are many unexplainable things such as the blind seeing when they leave their bodies. I accept that fact too, and live in peace with it.
I know my consciousness will go on and re-enter another body at the moment of birth. Can I prove it? That depends on whether you have an open mind and are willing to accept the evidence. Whether you believe in it or not, enjoy your immortality.
Live eternally through your love and know your consciousness will last forever.
