We do not profess to provide proof, witnessing a demonstration of mediumship should be viewed as an opportunity to gather your own evidence; it is for you to decide whether the evidence is substantial Sometimes we have to reach back in time to find acceptance of a memory link that is given, you may find that subsequently something that did not spring to mind during a communication will hold value later; you may hear the medium ask you to hold a piece of evidence if they are very sure of what they are giving you In time we hope you will gather sufficient evidence to swing the balance of your opinion to accept the concept of survival of the spirit
