The beautiful thing about such enlightenment is that the same capacity for abstract thought that serves to enslave the human mind with irrational fear over the disposition of one’s imaginary permanent self becomes the means of it’s emancipation through knowledge of the truth of one’s impermanence; and in that enlightenment, the mind that was previously one’s jailor becomes one’s liberator.
I am only familiar with Vipassana. Perhaps I misunderstand you but abstract thought is most certainly not a means of emancipation in this tradition. It is the capacity for non-identification with any thought. that allows space for meeting life directly, in the present moment, absent interpretations, projections, narratives, etc. Yes; we need the "gate-keeper" aspect of mind to watch the breath and identify the mental states/qualities that arise but this is not "abstract".
