Some people are still deeply entangled in the gunas. They work hard, they enjoy rewards, they suffer losses — all within the world of prakriti. Their understanding of the bigger picture is incomplete. Krishna says: do not shake these people out of their orbit prematurely.
A good teacher meets the student where they are, not where the teacher is. If someone is sincerely devoted to their work but does not yet see the deeper truth, the wise response is patience. Guide them gradually. Let them grow. Dumping the full weight of Vedantic wisdom on an unprepared mind does more harm than good.
