Reiki Blitzing
Yutaka Shaun Wada gave reiki attunements all over the place including escort agencies, and prostitutes so that they would quit their profession and live a wholesome spiritual life. He has given them to people at Starbucks coffee shops, Shopping malls, wherever people want to try out a Reiki attunement to have a loving channel for the rest of their lives.
mass-attunement:
The best way to attune people and get lots of practices is to have the right attitude. Keep in mind that you are doing something for the benefit of others. If you really understand that you are giving something, then in reality if they choose not to accept an attunement it is their loss and not yours. They are missing out. If you really, really understand that then you will never have a fear of rejection, which is the biggest reason which stops people from attune others.
When you understand that then doing lots of attunements is really easy. This is what usually happens with me:
Me: Hi have you ever heard of reiki before?
Them: Nope
Me: It’s a Japanese healing modality, we are just out today giving people attunements to assist them with their health and well being. Just hold your hands like this.
Me: (Then I put my hands in a cup position like I would like them to do)
Them: (They copy me and non verbally give their consent to do the attunement)
Once the attunement is finished then I will answer all their questions about it. Generally after a person has received it they are much more open to learning more about reiki than before. If you talk too much about reiki before the attunement then they think it’s a very big deal which needs lots of consideration before they ‘decide’ to do it or not. If you make it a big deal then they will. If you make it really simple then they will just put their hands out.
If someone really doesn’t want an attunement they will tell you, or get into an argument about it. Honestly don’t waste time with a ‘hard sell’. If you spend an hour trying to convince someone to receive an attunement who doesn’t want it, then you are missing out on dozens of other people who would have been more than happy to receive one. It will also lead to burn out much faster.

Last notes: The undisputed master of blitzing is Yutaka, he would be more than happy to go out with you and do some street blitzing when he has the time for it. But for that you would have to talk to him (almost always available at the club times). I would also recommend that you try doing it down at the booth when we have one. It’s much more comfortable to start practice doing reiki attunements at the booth as it’s a more formal atmosphere and you have other practitioners to help you out too.

Intend to attune, start with the hands, draw all symbols of traditional Usui symbols.
then the crown, all 7 chakras, and feet, then back, and back to the hands again.
4,531 people tried it with Yutaka Shuan Wada, and it was fine.
Not surprisingly, many RMs in that forum weren't too pleased with this idea. However this hasn't stopped the Reiki Blitzers. According to the latest post from bex:
Hi, Yutaka Shaun Wada finally hit 4002 today in attuning new people, and 2515 people in those who were attuned by someone else previously, at 6,517. His student Chris who attuned over 153 new people and 182 people who were previously attuned at over 335 people does give attunements only if the person gives permission. Some say he is Joshua Corber II in that he is going to do in Vancouver, what he did in Edinburgh, UK. Now, the discussion is that, Yutaka teaches that if you attune them first, all the healer's crap goes through a nice healing cycle so that they will have less issues stored in them thereby becoming a more positive healing channel. It is important that they get fully attuned over and over again so that they channel strong and clean energy to their client. Also, fully attuning the c
