Hi meljen,
The training I received was Usui Shiki Ryoho Reiki. I was taught that this simply means Usui Reiki. Here is a link that you may find helpful:
http://www.reikiassociation.org.uk/definition.htmlThe symbols are a tool which help us to learn focus in Reiki. I firmly believe that no matter what way you are taught, you should learn the symbols, what they are for and how they can be used. The reason you need to learn the symbols is to have the knowledge necessary to hand down complete information to your students or anyone who asks you about Reiki. But equally important you should learn to follow your own instincts as to how/when/if to use the symbols. What you are taught from your Master are the general guidelines. So much of Reiki is based on instinct, and each individual treatment session.
Reiju is a method of empowerment. Basically it is the same as an attunement. It is said Usui did offer Reiju to his students throughout their learning.
There is a lot of information available with regard to Traditional versus Western Reiki. If you feel compelled to study the more Traditional lines, then focus your searching there. Be prepared though, there is much overlap between the two and it is sometimes hard to discern which is which.
As for a 'style' of Reiki to learn, I truly believe that Usui Reiki is the best place to start. Whether it is dubbed Usui Shiki Ryoho, or Usui Reiki Ryoho, the basis is the form of Reiki that was brought to the public by Mikao Usui. I would always advise people to learn this first, then when enough time has elapsed and they wish to explore more, to go on to other modalities.
Have fun on your search meljen!
With light and love,
