Kaliya Nag and Krishna, in a poem from Vrindavan, Sri Banke Bihari ji ke sawaiya, 49 of 144
कारेइ मोहन कारेइ सोहन, कारी कालेन्दजा के तट आयो।
खेलत गेंद गिरी दह में तब कारे से नाग लो जाय जगायो॥
नाग को नाथ लियो छिन में अरु कारे के सीस पै नृत्य करायो।
‘गोविंद’ यों प्रभु शोभा बखानत कारे कौ नाथ के नाथ कहायो॥४९॥
This Sawaiya verse depicts the episode of Kaliya-manthan in Vrindavan. Poet Govid says:
“Krishna was playing with a ball with his friends on the banks of dark, deep waters of River Yamuna, when his ball fell into Kaliya-dah, a part of the river where Kaliya Nag, the thousand-headed snake lived. Krishna fought with Kaliya and emerged victorious, dancing on Kaliya’s heads. I cannot describe in words the awesome scene…”
Kaliya Nag is a symbol of the 5 senses, and the episode signifies that the master of the senses should be Krishna, else the waters of life would be poisoned by the craving and misery that the senses are capable of bringing, just like the presence of Kaliya Nag in Kaliya-dah, Vrindavan, poisoned the fresh river water.
