As you progress down the road to enlightenment, your false personality will begin to cause you pain, it does not like it that you are progressing and leaving it behind, so it starts to cause you pain in one way or another, your back or certain muscles in your body will be or get sore for no apparent reason, causing you much discomfort just to get you to stop what you are doing.
This is a part of the bio programming that has been prearranged before your life even started, it is there to test your mettle so to speak, another challenge placed to discourage you from ignoring your false life,
it is relentless and will stop at nothing to distract you from your focus, it wants you to quit what it is that you are trying to do, you see this game is played on level 10 all of the time, and it will not let up,
the best thing to do is to ignore the pain, especially if you know that there is no real good reason for it, and eventually it will fade away.
There is also a possibility that the pain is due to "wrong thinking" or "wrong actions" on your part, and your soul is trying to modify your behavior in some way, in this case it is a good thing that you use your observant self to analyze your actions to see if you are making mistakes somewhere.
It may be completely unavoidable to have pain for one reason or another, I noticed that for most of my clueless life I was without pain, my false selves were happy with the status quo, but as soon as I began to lift that veil of ignorance and started to see the truth about reality,
the pain started, it wanted me to just stay in bed and ride it out until I got better like it was some sort of illness that needed to run it's course,
exercise of different types seemed to do something to a point, but the pain continued to return day after day whether I liked it or not, it seemed to be best to ignore it for the most part and ride it out until it was totally forgotten and finally went away.
The pain subsides when it realizes that that part of you has been changed and is not going to change back, but lo and behold it returns when you make a new revelation about your self or another change that one of your false selves just doesn't want to let go of,
it's a continuous tearing down and building up process that in my case anyways is painful, mostly annoying, I just look at it as being another test to see how dedicated I really am at finding the entire truth of reality.
JUST DON'T GIVE UP!, you were given free will for a reason, once you realize this and that there are no things that can sway you from your path, the behavioral modifications that you are trying to implement become easier and easier.
There will be times that you just cannot reason why you have pain and it just doesn't go away, it may also be that you are burning Karmic ribbons from some previous life, where you have to feel this pain to equal out the imbalance you created, possibly in this life time or a previous life where you gave someone some pain,
if you can ask your true self or God or your spirit guide to show you or explain why you have this pain, you may be fortunate enough to get an answer in the way of a visible encounter that explains the situation in a way that you may understand.
In my case one time, I was shown in a dream a sort of trough at the beach that went into the ocean and was being flushed by the waves, it had large rocks in it that were seemingly being washed by the surf coming in, it looked cool and inviting, I went closer and noticed that something shiny was washed ashore, when I looked at it, I noticed that it looked like an old mercury dime, but upon closer inspection I noticed that it really wasn't, one side was different and it was made of aluminum instead of silver,
in my mind, this told me that a false portion of myself was being washed away and cleared out, as if the trough was me and the waves were cleansing me, I all of a sudden thought that I would Fast for that day,
I really never had fasted before, even 24 hours, and for some reason I felt like doing it now, it is hard to explain, but the fasting would be a type of spiritual cleansing that I needed,
also with my analysis from my observant self, I remembered that I had been having some discomfort in my stomach for the last couple of weeks, and I knew that my diet was not so bad,
I wasn't afraid since Gandhi had fasted for long periods over 30 days without permanent damage, I wasn't going to try to break any records, but I figured that 36 hours would be a good start, and then I would see about longer periods if the results were to my liking.
I understand that pain may be unavoidable as your enlightenment progresses, but when you understand that this may be required or expected especially if it is physically unwarranted and be the cause of something you may have an idea about, it should make it much easier, just hang in there and you will end up better for it in the long run.
I have also heard that pain is not at all necessary for enlightenment, but our souls use it because it is effective for thought or behavioral modifications when the stubbornness of our thoughts and actions are delaying our progress.
By the way, after my 36 hour fast, the back pain and stomach discomfort had completely disappeared, I have tried to make fasting a regular spiritual cleansing for my self, my wife does not understand it and worries, I have made it up to 62 hours so far, but I wish to make sure that I am in very good health and weight before I try to exceed that amount.
