Krishna delivers His final verdict regarding the debate from verse 3. He unequivocally sides with the active path: acts of sacrifice, charity, and penance must never be given up (na tyājyaṁ). They must absolutely be performed (kāryam eva tat). Why? Because these specific acts (yajño dānaṁ tapaś) act as supreme purifiers (pāvanāni) even for the most highly elevated and wise souls (manīṣiṇām).
