Generally for Removing Pain, We Cut only the Branches Not the Roots.
When We are in Deep Sleep We are not aware of the Physical Body.
Then there is No Pain.
Pains are Dependent on Ego.
Without the feeling of " I " Pains Can't Exist.
But " I " Can Exist.
Our Pain Changes with our Mental State.
When We See our Loved One's our Pain Ceases.
When We meet a Person whom We don't Like - Our Pain Increases.
Inquire within, Identify The Atma, Then all Pains associated with This World will Go Away.- Sri Ramana Maharshi..
