तत्रैवं सति कर्तारमात्मानं केवलं तु यः।पश्यत्यकृतबुद्धित्वान्न स पश्यति दुर्मतिः॥
tatraivaṃ sati kartāram ātmānaṃ kevalaṃ tu yaḥpaśyaty akṛta-buddhitvān na sa paśyati durmatiḥ
Word by word
The verse says
Given that, whoever looks at all this and sees himself alone as the one doing it, with his understanding unformed, does not see at all.
In plain words
Now the conclusion, and it is sharp.
If five things cause every action, then the person who sees only himself in there is missing four of them.
And the word used is not wicked. It is akṛta-buddhi - understanding not yet made, not yet finished. The problem is a half-built instrument, not a bad character.
Where you've felt this · in failure
A young manager takes over a team that has run well for years and within a month is telling people how he would like things done. The team keeps running well. He believes he is the reason. Two of the people actually holding it together leave within the year, and only then does the question of what was carrying what come up.
Going deeper
Being the sole author of your own actions is the belief under examination, and it is treated as a perception error rather than a sin.
The phrase is unformed understanding. Something has not finished developing. That framing is generous and also more accurate than calling it arrogance, because plenty of people who hold this belief are not arrogant at all. They simply have not counted.
The cost of the error is not only to other people. If you are the sole cause of your successes then you are also the sole cause of your failures, and that is a crushing thing to carry. The ego of the doer inflates the good days and makes the bad ones unsurvivable.
So the correction on offer is not humility as a virtue you should cultivate. It is just the right number, and the right number happens to be easier to live with.
