Most human beings spend their lives battling with opposing inner forces: what they think they should do versus what they are doing; how they feel about themselves versus how they are; whether they think they’re right and worthy or wrong and unworthy. The separate self is just the conglomeration of these opposing forces. When the self drops away, inner division drops away with it.
Most people don't get out of childhood, or adolescence, without being wounded for telling the truth. Someone says 'you can't say that' or 'you shouldn't say that' or 'that wasn't appropriate' so most of us human beings have a very deep underlying conditioning that says that just to be who we are is not OK.......Most human beings have an imprinting that if they're real, if they're honest, somebody's not gonna like it. And they won't be able to control their environment if they tell the truth.
It is not the pursuit of greater and greater states of happiness and bliss that leads to enlightenment, but the yearning for Reality and the rabid dissatisfaction with living anything less than a fully authentic life.
