प्रसीद लङ्केश्वर राक्षसेन्द्र लङ्कां प्रसन्नो भव साधु गच्छ।
त्वं स्वेषु दारेषु रमस्व नित्यं रामः सभार्यो रमतां वनेषु॥

prasīda laṅkeśvara rākṣasendra
laṅkāṁ prasanno bhava sādhu gaccha
tvaṁ sveṣu dāreṣu ramasva nityaṁ
rāmaḥ sa-bhāryo ramatāṁ vaneṣu

O lord of Laṅkā and ruler of the rākṣasas, be happy! Be content with Laṅkā. Tread the right track. Be happy with your own wives and let Rāma always be happy with His wife in the woods.
