People are coming into this confused about the particulars of their experience. However one can generally notice feelings of apathy, general vexation associated with fear, regret, shame, anxiety, worry, anger, lust, confusion and etc. One may want to get rid of these in near future.
Even tho we may not be able to immediately identify why we feel a certain way and what to call a particular sensation, we may assert that our behavior has not been optimal as to result in that and to implement Buddha's teachings in order to start our training of good behavior.
Good behavior starts in abstaining from behaviors that are a cause for regret & downfall. It is essentially so that our understanding should come to be with a sense of fear & shame of wrongdoing.
In avoiding the bad behaviors we are engaging in skillful development of the intellect and are avoiding bad consequences of the foregone bad behaviors which avoids that trouble and allows us to calm down due to non-regret. We can reflect on our success in that and be gladdened before further stilling & learning through meditative composure and on account of due contemplation.
Our brains rewire all the time as cells are replaced & new networks are formed. We can rewire a lot in say about 7 years such that there are no pathways left by which evil behaviors associated with greed, anger & delusion would exist.
There is a part to Buddhism which is paradoxical, going against norm and it is the reason why it was never enough for every person to just have the Dhamma explained to them. Not to downplay the importance of proper translations but even when Buddha explained it many would not be able or willing to see the point he was making because for a long time they relish opposing views.
There is a point of convergence between those who know and those who do not know in the ability of one to guide another going by faith in one's ability to train.
One must learn a lot a and do as the teacher said as to see the results of that properly undertaken training and it's point. This would require some sort of a full time dedication to development of good behavior in a long-term retreat environment.
