आत्मनः मुखदोषेण बध्यन्ते शुकसारिकाः।
बकाः तत्र न बध्यन्ते मौनं सर्वार्थ साधनम्॥
ātmanaḥ mukhadoṣeṇa badhyante śukasārikāḥ |
bakāḥ tatra na badhyante maunaṁ sarvārtha sādhanam ||
"By the fault of their own mouth, parrots and mynahs are caught.
Storks, however are not caught — silence is an instrument that achieves all ends."
