Spirit. Voice contact
I was just thinking about how mediums use spirit guides to interpret spirit messages. The reason being that spirit resonates at a different vibrational level to ourselves. The spirit guide acts as interpreter. So when we use EVP or 'ask out' for answers, how do we know that spirit understands what we are saying? If we need a means of interpretation for their messages how do we know that they don't need the same? Perhaps this could be why we rarely get response to 'asking out'. They may not be able to receive our message due to distortion, etc.
