ज्ञानं कर्म च कर्ता च त्रिधैव गुणभेदतः।प्रोच्यते गुणसंख्याने यथावच्छृणु तान्यपि॥

Word by word
The verse says
Knowledge, action and the doer are each of three kinds, divided by the strands of nature. Hear about them properly too.
In plain words
The blade comes out again. Three more things are about to be cut into three.
Knowledge. Action. The doer. Each one sorted by the three strands.
And notice what is included: the doer. You are about to be sorted too, which is less comfortable than sorting your activities.
Where you've felt this · in study
A driving instructor can tell within ten minutes which of three kinds of learner is in the car. The one who is careful and a little slow. The one who is quick and wants to overtake already. The one who has not really looked at the road yet. All three are trying. The lesson is different for each.
Going deeper
Including the doer in the list of things to be sorted is the step that makes this chapter personal rather than academic.
It is comfortable to classify your actions. You stand outside them and grade them, and whoever is doing the grading stays untouched. Putting the doer in the list removes that vantage point. The one doing the sorting is also an item in it.
This is the same move Chapter 14 made when it said that clarity itself binds, and binds through the pleasure of understanding. Knowing the three strands does not place you above the three strands.
What follows from that is a kind of permanent provisionality. Whatever conclusion you reach about yourself was reached by an instrument that is itself coloured, so it is worth holding a little loosely. That is not scepticism. It is just knowing what you are working with.
