Hi...I have only been attuned by distance. As Mickuk says most everyone agrees on the fact that they are both good. I was attuned in Sept. to all three levels and I was lucky enough to have joined in with a group where the woman was doing a singulatr attunement on Christmas day. I went ahead and did the attunement again not because I felt I didn't receive it the first time but because I have come to know the woman through the group and have felt a warm, loving energy from her...So she did it again...I was a little worried about the cleansing process but you know what? Once you are on the path, and it sounds like you are, spiritually you are constantly cleansing any way...you are going to go through the same feelings as if you were were attuned. As the light works it's way through your thought process you are going to clear out the gunk and clutter...you are going to look back on your life, the regrets the whatever and deal with it because you want to be the person you were meant to be...Make sense??...so what I'm trying to say is go ahead and do a three level singular attunement, start with one Reiki...Usui Reiki, i would suggest...download your manuals( Link to Free Usui Reiki Manuals All 3 Levels, check "General Discussion" Board) and go at your pace...Reiki is gentle and will work with you...It will not overwhelm you...you start with the daily self treatment...pictures are in the manual... And live by the precepts :do not anger, do not worry, work honestly, Honor yourself and others, be grateful....I use these five but add to them a bit and I repeat them through the day. Also there are quite a few of good Reiki groups out there...If you'd like a list to different groups You can email me off site and I'd be happy to send them to you...Welcome to Reiki...Mickuk and Nitya have years of experience and there are others that post with good advice as well...Happy learning...Blessings jeanie
