I was once in that state for quite a long time. I found the peace of mind. I got rid of the fears. Not feared what other would think about me, fear someone could kill me (rough neighborhood). Basically, I broke my ego. I was being honest with myself. It was really a blissful state.
But it wasn't for the right reasons....I thought I cracked it and that now I am smarter than others, forgetting to continue to get rid of my ego, which is still there somewhere, hiding.
Eventually I became very frustrated when I tried to explain, people close to me, how to attain this state.
First, I got it wrong for the reasons, I was in peaceful state, where not exactly spot on.
Second, I got some very nasty retaliation from people I loved the most (not romantically). Basically they tried to attack my weak spot with such a force, I couldn't take it, my new ego took a hit and my peaceful mind went to hell in a second. It took me few months to be out of the worst. I was fine, certainly better than in the beginning but I was afraid again not to replay the nasty part. So I plugged myself back to matrix....now sort of seeking material fulfillment (I was never much of a fan of $). I sort of succeeded and now hopefully, I am regaining balance again and working on my peace of mind, while doing the world a better place, keeping check on my ego.
I hope some of you can learn the lesson from my story, especially the part Do not to forget to keep the ego safely tied at all times. By Ego I mean false identity your mind creates to rationalize your existence. Learn to shut it down and when you need to think always check on the ego - be extremely honest with yourself.
