ANSWER – I am very sorry for the loss of your mother and appreciate that even three years later this must still be a very difficult time for you.
I wanted to answer this question because I think it is the kind of question that a lot of magical/spiritual sites answer badly and I believe it is very important that people with genuine grief are not exploited by (witches or otherwise) people who would look to use that grief to serve personal gain.
I am therefore sorry to tell you that I am unable to offer any information relating to your mother after her passing. Much as I would like to be able to offer you comfort by telling you with certainty she is content in an afterlife I do not have the facts to back up such a confident assertion.
There are genuine mediums whom I firmly believe have the ability to contact the dead. However for every genuine medium there will be twenty others who believe they have the gift or who lie about having the gift. In a matter as personal and emotionally charged as contacting a relative who has passed over it is my belief you should research very thoroughly anybody you intend to trust to assist you in this. Even a genuine medium would struggle to give you any valid information based on a question via a website. The best mediums would want to get to know you, to understand a bit about your mother and who she was, learn her name, perhaps handle her possessions. I doubt even the very best mediums would be able to give you any kind of genuine answer in relation to your mother based on the very limited information I ask for on the Ask a Witch a Question submission form.
Guard against being too quick to trust. It would be very easy for an unscrupulous website to write back and say – Mother is doing fine, send me £100 and I’ll tell you more details. Some, sadly, would reply in exactly this manner.
Having said that I am happy to share my beliefs with you with the understanding these are beliefs and not esoteric knowledge based on my abilities as a witch. I believe that when people pass over they go into a period of rest state while they prepare for their next life in this world. I genuinely believe they retain the links they made with others in their previous lives and that these human soul based relationships will replay themselves in other incarnations at other times. I believe death is a necessity for the human soul to be recharged and rested before undertaking the effort of beginning a new life and a new existence. I see death as a positive phase of rejuvenation, the gathering of energies toward a new direction and a new purpose.
With these beliefs strongly at the forefront of my mind I would guess your mother to be rested and at peace.
