saleem,
Hi.
You might also post this healing request at the Healing Requests Board if you have not already done so. More practitioners may see it there.
Anyone trained and attuned to Reiki 2 can do the distance work though not everyone has equal skills. Being called a reiki master does not automatically improve this.
And some Reiki Masters are women. Several of the more talented reiki practitioners I know are women.
I wonder if your wife as had some sort of stroke? Does she know you have asked for reiki for her?
Cheers,
RC
