What is positive, i feel, one becomes more oneself. Some believe this means i have identity view, maybe, i feel it is like this.
When you are a person with strong tendencies, urges, inner floods, impetus, you are often unsatisfied while you react on them. When you start to react in a insensitive, instinctive, crude way on situations and other people. Those inner floods, when they are overwhelming, it leads you as person into a process of self-alienation and becoming insensitive. Your behaviour is not really wise anymore.
Those inner urges which the Buddha described as tanha, asava, anusaya are like floods which overwhelm one. And often at that moment you are not the best version of yourself. You become insensitive, loose your wisdom. The results are not good.
While those inner floods, those urges, weaken due to Dhamma you are more yourself. Nothing is lost. Only becoming insensitive gets lost. You do not get lost.
I believe this means that while we become more and more pure, and our behaviour is less and less instigated by urges, inner floods, becoming less and less attached, we only become more and more ourselves. That itself is a kind of reward and nice. It is nice to experience one does not become a madman anymore, insensitive, because that is dukkha for oneself and others.
By the way, the expression ‘being oneself’ does not mean one has self views, or ego conceit but it means that one does not get lost in the inner floods anymore. One does not self-alieniate and stay sensitive in contact with the world.
Nibbana is ultimate sensitivity and that is its cooling down and happiness.
