Can a person's body and consciousness so change during his lifetime that he becomes fit for a finer soul to enter him?
A finer soul does not enter him. But if the person's body and consciousness are transformed totally, then the soul that he already possesses will be in a position to fulfil its divine mission here on earth most effectively, in all its supernal Perfection.
