SB 10.11.12
sarit-tira-gatam krsnam
bhagnarjunam athahvayat
ramam ca rohini devi
kridantam balakair bhrsam
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Once, after the uprooting of the yamala-arjuna trees, Rohinidevi went to call Rama and Krsna, who had both gone to the riverside and were playing with the other boys with deep attention.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Mother Yasoda was more attached to Krsna and Balarama than Rohinidevi was, although Rohinidevi was the mother of Balarama. Mother Yasoda sent Rohinidevi to call Rama and Krsna from Their play, since it was the right time for lunch. Therefore Rohinidevi went to call Them, breaking Their engagement in play.
