A few hours ago, Archangel Raphael came to me and gave me this message (I did not perform any ritual or invocation) :
Let others know that I can heal them. Let them know that others can heal them. Just ask, we always listen and we will help. Sometimes nothing is required, sometimes you may have to offer something but we are always willing to help.
He told me that I should post this here. I am currently working with him on a few health issues and will be performing a healing meditation with him at least twice a month.
