Question: Where in the body is the spark of the soul? How can I feel that it is really inside me?
Answer: The spark is not in a person’s body. There is no such place in the body that you can cut and remove from it.
It is a spiritual force that is not in the corporeal body. Even if your body ceases to exist, the spark will still remain and will acquire a new corporeal body. It is the spiritual gene that exists permanently and is passed on from one life to the next. The only thing that changes is its corporeal carrier.
