PURPORT

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.
