Please correct me if I'm wrong.
From what I read, the purpose of Vipassana meditation is to get insight, and wisdom about one self, in order to achieve a better life and eventually nibanna.
The way I have been taught to practice Vipassana, is to focus on the present moment, feeling the sensations or emotions as they appear and disappear, observe the changes in the mind, and so on.
However, in order to get insight, am I not supposed to analyse what is going on, looking for answers ? In order to think in that way, isnt'it necessary to break the focus on the present moment and therefore break the meditation ? Maybe it is part of the meditation ?
As an example, suppose that I am meditating. Suddently a feeling of anxiety arises. I turn my focus to this feeling, gathering informations, feeling it for what it is, seeing the impermanence in it, etc. Then the anxiety disappears or some other thing arises, so I need to switch my focus in order to stay in the present moment.
Instead, I would like to investigate this feeling, trying to guess why it happened, seeing if there is a way I can prevent myself from feeling it again, or if there is a way to prevent myself from the suffering I create by repeling this feeling.
Experience as shown that I can get to great insight by interrupting the focus on the present moment to investigate the feeling. However on some other occasions it distracted me. In addition I imagine that the insights I get may be sometimes incomplete or false views ?
How I am supposed to go about this ?
