Srimad-Bhagavatam

SB Canto 10.1 to 10.13

Nanda Mahārāja's wonder may be understood in various ways. First of all, the cowherd men had never before seen such a gigantic body in Vṛndāvana, 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 yoginī, they had come to some place other than Vṛndāvana. They could not actually guess what had happened, and therefore they were struck with wonder.
