yayor janmany ado visvam
manamsi kakubho vatah
praseduh sarito ’drayah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
On the occasion of the appearance of Nara-Narayana, the entire world was full of joy. Everyone’s mind became tranquil, and thus in all directions the air, the rivers and the mountains became pleasant.
