यया धर्ममधर्मं च कार्यं चाकार्यमेव च।अयथावत्प्रजानाति बुद्धिः सा पार्थ राजसी॥
yayā dharmam adharmaṃ ca kāryaṃ cākāryam eva caayathāvat prajānāti buddhiḥ sā pārtha rājasī
Word by word
The verse says
The understanding by which you get right and wrong, and what should and should not be done, the wrong way round: that one, Arjuna, is driven.
In plain words
The middle kind. It is trying to tell right from wrong and it is getting it wrong.
Not refusing the question. Not indifferent to it. Working on it, and arriving in the wrong place.
That is the specific failure of this strand throughout the book. Effort is present. Accuracy is not, because something is pulling.
Where you've felt this · in relationships
Your friend is sure she was right in an argument with her sister, and she has a strong case, and she tells it well. Three months later, with the heat gone, she says out of nowhere that she thinks she was probably the one being unfair. Nothing new came to light. She simply stopped needing a particular answer.
Going deeper
Judgement that is active, sincere and reliably skewed is what this names, and the skew has a direction.
This is not confusion. A confused person does not know. The person described here does know, confidently, and is wrong, and the wrongness is not random. It leans towards whatever they already wanted.
That is what the driven strand does to understanding. It does not switch the faculty off. It puts a thumb on it, and the thumb is invisible from inside, because the resulting judgement feels exactly like any other judgement.
The only thing that reliably puts this right is time or distance, which is why your own verdict on a dispute is worth much more three months later. It is also why the one useful question in the middle of an argument is not am I right, but whether you would still reach this conclusion if the answer cost you nothing.
