After death, there is a period of time for which the portal of light opens and your loved one can go into the light and reincarnate to another existence.
Due to various reasons (unsettled business, fear of moving on, etc), your loved one may stay on to Earth instead of going into the light. Once the portal closes, they would be stuck here forever unless an opportunity presents itself.
In this gig, I can test whether your loved one has indeed moved on into the light and if not, I would help him/her to do so.
To get reassurance that your loved one is in some place safe... it's priceless!
