The basic approach to the ARI [R. Isaac Luria] that I hold with is the Reshash--Sar Shalom Sharabi. In fact I prayed with the small sidur of the Reshash for years, and later I found the larger one.  But at some point I decided to go on the path of R. Akiva who according to the gemara ''entered into the higher worlds in peace and left in peace.''--Not that I have anything against being in a state of ''devekut'' [attachment to the infinite light''], but rather I felt one needs the proper ''vessels'' to be able to hold the light-or risk breaking of the vessels. 

[I Also agree with the approach to the Ari of Rav Yaakov Abuchazeira and the Ramchal. Rav Yaakov is the simple ''peshat'' [explanation], while the Reshash is Tosphot. The Ramchal fills in some detail and provides a wider context]
