I've been attuned to level 2 reiki. I've also received it a few times both in person and from a distance. And stone me, but I felt stuff every time. The first time I had it from a master on my crown it was like something pouring down through my body. It felt electrical and great.
I've no idea how the distance stuff works, although I've been told how to do it. Well, I've been given explanations about the 'all-is-one, time and space is an illusion' stuff, but I'm still waiting on that experience for myself. But now my mind is well and truly open.
If you can reliably distinguish whether the distant practitioner is doing anything to you or not, you should be able to get yourself a million dollars [0].
