Caitanya-caritāmṛta 3.27
aho bhāgya, yamunāre pāiluṅ daraśana eta bali’ yamunāra karena stavana
[aho bhaagya, yamunaare paailun darashana eta bali’ yamunaara karena stavana]
Blended reading (Sanskrit + English inline)
aho bhāgya, yamunāre pāiluṅ daraśana eta bali’ yamunāra karena stavana
The Lord said, “Oh, what good fortune! Now I have seen the river Yamunā.” Thus thinking the Ganges to be the river Yamunā, Caitanya Mahāprabhu began to offer prayers to it.
