त्रैविद्या मां सोमपाः पूतपापा यज्ञैरिष्ट्वा स्वर्गतिं प्रार्थयन्ते।ते पुण्यमासाद्य सुरेन्द्रलोक मश्नन्ति दिव्यान्दिवि देवभोगान्॥
trai-vidyā māṃ soma-pāḥ pūta-pāpāyajñair iṣṭvā svar-gatiṃ prārthayantete puṇyam āsādya surendra-lokamaśnanti divyān divi deva-bhogān
Word by word
The verse says
Those who know the three Vedas, who drink the soma, who are washed clean of wrong, worship me with sacrifices and ask for the way to heaven. Reaching the holy world of the king of the gods, they enjoy the pleasures of the gods.
In plain words
No mockery here, which is worth noticing.
These people do the work properly. They are described as cleansed of wrong. They ask for heaven and they get heaven.
The system is being described as working exactly as advertised.
Where you've felt this · with money
Your father put money into a scheme for fifteen years and it paid out exactly what it had promised, to the rupee. Nothing was mis-sold and nobody was cheated. He got precisely what he had bought, on the date he had been told, and it was a reasonable thing to have bought.
Going deeper
Describing something accurately before disagreeing with it is a habit this book keeps, and it is on display here.
The ritual system of the time promised results for correct performance. Krishna does not say the promise was fraudulent. He says it is kept. The sacrifices work, the merit is real, the heaven is reached and enjoyed.
That matters for how the criticism in the next verse should be read. It is not an exposure. Nobody is being told they were fooled.
There is something worth borrowing in the approach, quite apart from the subject. The strongest form of a disagreement states the other position at its best first, and it is noticeable how rarely anybody does that. The Gita does it to the dominant religion of its own time, in a chapter that is arguing against it.
