The main system of Rav Sharabi you can learn in his book the Nahar Shalom. However I found for myself that simply praying with the sidur HaReshash for a few years helped me get a clearer idea of his system.[I ought to mention that I was praying with the sidur of the Reshash for the unification--not to gain better knowledge of his system.]
[There are two sidurs of Rav Sharabi I ought to mention. For a long time I prayed with the small one even though I knew that Rav Mordechei Sharabi said there were mistakes in it. And in any case I felt, it was less accurate than I needed. Then one great day I was in Mea Shearim in Jerusalem and discovered that in some private home there, the family was selling the actual large sidur of the Reshash.]
It is known that the Gra said that the Ari is speaking in terms of an analogy, not literal like he sounds.
