ekada carayan vatsan
sa-ramo vanam avisat
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One day, five or six nights before the completion of the year, Krsna, tending the calves, entered the forest along with Balarama.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Up to this time, even Balarama was captivated by the bewilderment that covered Brahma. Even Balarama did not know that all the calves and cowherd boys were expansions of Krsna or that He Himself was also an expansion of Krsna. This was disclosed to Balarama just five or six days before the completion of the year.
