I blew, I dont know, at least a good partial K, years ago after competely ignoring RB's advise against Over stimulating energy centers and the effects where substantial. They match more or less with the things you read about thoughout the web. Ofcourse thats what you get for acting irresponsibly lolol . There are however many good things that come about as a result of its "raising", even in my case where I wasnt the least bit prepared. It puts you in touch, albeit temporarily with apart of Something you had no idea about previously, and for me atleast, changed my life for the better forever. And besides In my case, I got warning signs that it was about to happen, you get HUGE HUGE energy spikes just before....Spikes you cant mistake for anything normal while doing energy work, you know when they hit ahhhh something seriously out of the ordinary is coming if you continue... It was kinda my last chance to stop the energy manipulations and cool it. Lol ofcourse once those kinda energy levels are pumping it is so tempting to keep it up and see what happens, the momentum being what it is. Yeah It blew my mind sky high for a couple hours, you get supper twitchy along your torso, much more sensitive to Any energies around you, disassociation was a big problem for me, ect..ect..ect.. and ofcourse symptoms start out heavy and fade/change over the course of a couple months. Not to mention lol the unbelievable abdominal slow motion twist/cramps you get at onset. One thing about it you sure Know when its happening lol. There's no guess work about that. The worst effect is it sets your Base on Fire for weeks. But it was all worth it for me. Im not so sure I would recommend it if you just chasing Phenomenon like I believe so many do (including myself at the time) but In any regard I would advise some level of Prep work. sorry for the rambling
