Which RB book is best for energy work?

I have been reading and doing the NEW articles/exercises on the website, the awareness stuff is simple for me but interesting, In the past I was less "precise" in awareness though. I keep getting sympathetic energy flows elsewhere - focus on my hands and I get waves up my legs, etc. Guess I have established/open paths, often a thought is all that is needed. The healing energy flow exercise is quite enjoyable and attracts my Cat like a magnet. :)
It's interesting for me as I have always brought energy down, through higher Chakra into my Crown Chakra for energy work.
Being so long since I did systematic clearing work (Zenith clearings) It would be good to work through the NEW system I feel.
Which book is best for energy work and the NEW system, for personal growth and opening abilities, I read mention of it being written about in several books?
OBE and Kundalina work possibly later, but ATM I need to get the basics sorted and deal with whatever is limiting my abilities :)

I like to start out with the free information from the website to get the basic stuff down first, and then get Energy Work, which gives you more specialization.

Thanks, going to work through that, though I initially thought it a dead link as it didn't load right away.
