SB 10.13.36
kim etad adbhutam iva
vasudeve ’khilatmani
vrajasya satmanas tokesv
apurvam prema vardhate
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
What is this wonderful phenomenon? The affection of all the inhabitants of Vraja, including Me, toward these boys and calves is increasing as never before, just like our affection for Lord Krsna, the Supersoul of all living entities.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
This increase of affection was not maya; rather, because Krsna had expanded Himself as everything and because the whole life of everyone in Vrndavana was meant for Krsna, the cows, because of affection for Krsna, had more affection for the older calves than for the new calves, and the men increased in their affection for their sons. Balarama was astonished to see all the residents of Vrndavana so affectionate toward their own children, exactly as they had been for Krsna. Similarly, the cows had grown affectionate toward their calves as much as toward Krsna. Balarama was surprised to see the acts of yoga-maya. Therefore He inquired from Krsna, “What is happening here? What is this mystery?”
