tavan nandadayo gopa
mathuraya vrajam gatah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Meanwhile, all the cowherd men, headed by Nanda Maharaja, returned from Mathura, and when they saw on the way the gigantic body of Putana lying dead, they were struck with great wonder.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Nanda Maharaja’s wonder may be understood in various ways. First of all, the cowherd men had never before seen such a gigantic body in Vrndavana, and therefore they were struck with wonder. Then they began to consider where such a body had come from, whether it had dropped from the sky, or whether, by some mistake or by the power of some mystic yogini, they had come to some place other than Vrndavana. They could not actually guess what had happened, and therefore they were struck with wonder.
