Pain has tentacles. It begins from heart, churn the blood and then reinforces each cell as these tentacles divides each milli second. This is not the medical version but the emotional version which is far easy to explain.
So, does pain helps? Yes, it do. How? These tentacles have the power to transcend conscious and reach subconscious! For each human when the subconscious wakes, they take the call! Acting on the call and resolving something to someone or self heals someone or self.
Pain is powerful, as our subconscious mind decides what we are made of and the tentacles takes rest only after a solution is at reach.
Wishing all of you to stay blessed with your conscious and subconscious minds in synch.
