भरते ब्रुवति स्वप्नं दूतास्ते क्लान्तवाहनाः।
प्रविश्यासह्यपरिघं रम्यं राजगृहं पुरम्॥

bharate bruvati svapnaṁ dūtās te klānta-vāhanāḥ
praviśyāsahya-parighaṁ ramyaṁ rājagṛhaṁ puram

bharate = while Bharata; bruvati = was talkig; svapnam = about His dream; dūtāḥ te = the messengers [sent by Vasiṣṭha]; klānta-vāhanāḥ = and hence unassailable; praviśya = entered; asahya-parigham = the city was locked on the outside; ramyam = the pleasant; rājagṛham = of Rājagṛha; puram = city.

While Bharata was talking about His dream, the messengers [sent by Vasiṣṭha] entered the pleasant city of Rājagṛha. The city was locked on the outside and hence unassailable.
