In that very beautiful land (of Vraja), where many cows reside, Rohini, the wife of Vasudeva, is living at the home of Nanda Maharaja. Other wives of Vasudeva are also living there incognito because of fear of Kamsa. Please go there - SB 10.2.7
SB Canto 10.1 to 10.13
The Lord ordered Yogamāyā: O My potency, who are worshipable for the entire world and whose nature is to bestow good fortune upon all living entities, go to Vraja, where there live many cowherd men and their wives. In that very beautiful land, where many cows reside, Rohiṇī, the wife of Vasudeva, is living at the home of Nanda Mahārāja. Other wives of Vasudeva are also living there incognito because of fear of Kaṁsa. Please go there.
Nanda-gokula, the residence of King Nanda, was itself very beautiful, and when Yogamāyā was ordered to go there and encourage the devotees with fearlessness, it became even more beautiful and safe. Because Yogamāyā had the ability to create such an atmosphere, the Lord ordered her to go to Nanda-gokula.
