And to answer both of your posts... there-in lies the problem.
You are assuming that because I use the word Reiki, that I am also teaching/learning/practicing Usui Reiki. Even if I profess to teach under Usui's lineage, does not mean that the teachings can't change.
You ever play the game of telephone? You know that when you have a "word-of-mouth" system, that things change after passing through several people. Each little subtle change eventually creates a major change. Its inevitable.
Now that doesn't mean that I'm going to go out and change the system, bank off Usui's name, and create a nice little monetary or "spiritual" windfall for myself. Some people obviously have done that.
As you can see, I've been attuned to several different energy systems that are fundamentally similar to Reiki in how the protocols work. I don't bill myself (actually don't really do any marketing for myself, which is probably why my clientelle isn't that large and I can't support myself on a Reiki practice alone) as a Reiki Practitioner as Usui would have done it.
I bill myself as an energy worker who happens to have access to Reiki, which supports the facilitation of a healing session, and helps the client relax and find their own healing being. I can also teach a class and attune you to Reiki.
But as you can tell by my posts, I have had some very strong experiences with my shamanic work. That is the lineage I wish to pursue more spiritual knowledge in. I believe that Reiki and shamanism work very well together. They synergize nicely.
I also feel that taking bits and pieces from different spiritual systems to fit a nice understandable conglomeration is beautiful. My shamanic teacher, who teaches and Incan tradition, has done extensive study in Zen Buddhism and other eastern indigenous practices. She has interwoven many meditation practices from Vedic, Buddhist, Yoga, and Incan into her teachings. She doesn't hesitate to tell you when a teaching is not pure Incan, that it is her own variation on combining two lineages. But the basis for her teaching is the Incan medicine wheel.
As for which energetic system can I find more information on?
Are you kidding me? I can go online and google or go to amazon and find at least 10 to 1, more English language books on Chakras than I can on the Japanese energy system.
Obviously you can't truly learn what a Chakra is by just reading a book. You have to experience it. And true knowledge only comes after a long period of time of experience and practical study.
But there is much more knowledge out there on Chakra's than there is on the Seika Tanden. If I can't find enough information on the Seika Tanden to feel comfortable teaching about it, then I won't teach about it. About the extent of what I can teach about it right now, is its location, and that it is probably a simplification and derivative of the Chinese or Taoist Dantien.
Remember back on Reiki-4-All I was about to do a "disertation" on the Seika Tanden. I had been all up in arms about this particular argument and was going to do my best to show you up. Obviously I didn't do that, because ultimately I realized that there is no point to penis-wagging when talking about Reiki and other spiritual matters when everyones opinion matters.
But lets not forget, that 90% of Japanese culture was gotten from China and then simplified. Thus the "Three Jewels" of the Dantien became the Seika Tanden. The Chinese simplified the Seven Chakra's from India into the "Three Jewels" of the Dantien. Just like when cultures migrate, languages change, "Gods" change, beliefs change, etc.
You can see that in the fertile crescent where one of the first cities was El, named after the father god of the Sumerian pantheon. Then came a city Enlil, and then Marduk. As civilization grew northward up the valley of the Tigris and Euphrates, the son's of the father gods became the new father gods.
In Egyptian mythology Isis left northward across the sea. In Greek mythology Aphrodite came from the south sea from the Island of Crete. They are both the goddess of beauty and love and female fertility. It is not a stretch to postulate that Isis and Aphrodite are the same goddess, just named differently by a different culture with a different language and different mind set based on environment and survival factors.
Wotan was the father god of the Germanic Celts. Odin was the father god of the Vikings. Both stories are so similar, that scholars postulate they are one and the same God, just with a different name.
In Hebrew, Jesus is Jeshua. Yahweh and Jehovah are both different Hebraic pronunciations of the same word for God.
My whole point about this last bit of ramble, is that Chakra's are as effective to study for the use of Reiki as the Seika Tanden is. Why? Because essentially they are the same thing. One just happens to be defined differently by the culture that defines it. But when you look at the basis of the definition, its still the same thing.
Its (they) an (are) energy organ(s) that help(s to) balance our energy lines, nodes, and bodies with our physical body. Even ties our physical body to our energy bodies.
Part of being a shaman is midwifery. That doesn't necessarily mean the assistance in the physical birthing of a baby. It means that you help people in transition. This can me in assisting someone to die. To help their spirit make the transition to the other side peacefully, with relaxation and bliss. One of the processes to do such includes much work with unwinding the Chakra's in a certain pattern and then, with intent, lifting them out of their body.
One of our workshops we did (the West, a year ago) we actually did a modified version of this on each other, so that we could experience our own deathing. Quite an emotional experience let me tell you.
All I'm saying is, I personally don't feel there is any problem with combining different spiritual systems together to create a synergized whole that is stronger than the sum of the parts.
I also believe that finding this synergy is a personal journey for each individual person (which I also believe you are saying.)
As far as teaching Reiki goes? If I teach a Reiki class, I will start with a basic level 1 class, which introduces them to who Usui was, his discovery story, who Hyashi was, who Takata was, and all their importance. I will teach the hand positions and how they coincide with both the endocrine glands and the chakras, and give a brief spiel about energy as I see it. I'll also discuss the ethics of energy work, especially as it pertains to work in the US.
That's about all that's necessary for a level 1 class. If asked, I will discuss my personal spirituality and how I apply it to Reiki and Reiki to it. How Reiki was a huge influence in gaining/achieving my spiritual place.
As a student gains in experience and confidence in their own work. I will teach them a level 2 class. The level 2 class would entail of course the three basic symbols CKR, SHK, and HSZSN. There are a few meditations we can also cover to help them bond psychologically to these symbols. To help them gain their own personal information from them. But largely, this is a class to deepen the experience. This is the class where the student usually will make the decision to be just a practitioner, or where they will seek the spirituality behind Reiki.
There are many, many good books out there. Amy Z. Rowland, Dianne Stein, William Rand, Walter Lubeck, Arjava Petter, and many others have wonderful pages of text on how to do Reiki, how to combine Reiki with other systems, how to incorporate Chakras, what the Japanese techniques and terms are, et. al.
But having a fundamental understanding of an energy system is invaluable when learning energy work.
I just don't personally feel that a specific cultural terminology is necessary over another. It is wholly dependent on which one speaks to the individual.
For you, apparently, it seems you have a crisis as to what you should focus your study attention to. You even said that you've stopped teaching because you don't feel comfortable that you know enough about the Japanese spirituality of Mikao Usui to do the class justice or do just honor to Mikao Usui. And that is fine.
But mentioning Chakras, and referring folks to texts about Chakra's so that they can treat Chakra's with Reiki, doesn't mean I'm not teaching Reiki. It means that I'm suggesting that Reiki can be helpful to Chakras as Chakras are part of the being. Even to balance your own Chakras can be helpful for you as a practitioner, for a more balanced practitioner will be more effective in assisting their clients.
Ok, I've rambled enough for now.
