Mujitsu and Tairaku's Shakuhachi BBQ

Hello all, 
Just the particulars’ - I have been playing for many many years -but have had no formal instruction.
I have several types of cane and bamboo flutes - But for meditation I prefer the Jinashi of 2.2 or longer -the lower ro's are more in tune with me.
I find that playing either deep in the woods or on a secluded section of the river is the most rewarding and peaceful. 
I recently found that I want to become much better educated about playing and understanding the history of the shakuhachi. So feel free to help me out.  Right now I am trying to learn how to read the music scores in "how to play the shakuhachi flute" a daunting but not overwhelming task because my mind keeps wanting to "just play" and not follow the score -

     I play shakuhachi to practice breath control/breathing meditation -and as such sometimes the free form and colorful sounds my flute and I create seem to come from somewhere else -but I believe thats because I cease to exist, "my" consciousness goes somewhere else where the flute and the body are far behind.
 
Good to meet you all -

O
