Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The most fortunate Rohini, the mother of Baladeva, was honored by Nanda Maharaja and Yasoda, and thus she also dressed gorgeously and decorated herself with a necklace, a garland and other ornaments. She was busy wandering here and there to receive the women who were guests at the festival.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Rohini, another wife of Vasudeva’s, was also kept under the care of Nanda Maharaja with her son Baladeva. Because her husband was imprisoned by Kamsa, she was not very happy, but on the occasion of Krsna-janmastami, Nandotsava, when Nanda Maharaja gave dresses and ornaments to others, he also gave gorgeous garments and ornaments to Rohini so that she could take part in the festival. Thus she also was busy receiving the women who were guests. Because of her good fortune in being able to raise Krsna and Balarama together, she is described as maha-bhaga, greatly fortunate.
