वीरे warrior, कपीश्वर O lord of monkeys, अज्ञानात् by ignorance, लाघवात् due to thoughtlessness, त्वयि विपन्ने in your danger, मया by me, मम my, मौढ्यं च folly, बाल्यं च childishness, ख्यापितम् revealed, स्यात् will be.

'O lord of monkeys I would have betrayed my foolishness and childishness had I exposed you to danger by my ignorance and thoughtlessness.
