Pradyumna: Translation: "King Parīkṣit married the daughter of King Uttara and begot four sons, headed by Mahārāja Janamejaya." (SB 1.16.2)
Prabhupāda: Sa uttarasya tanayām. Mahārāja Parīkṣit, his mother's name was Uttarā, Uttarā. Means King Virāṭa, he had two issues, one son, one daughter. The son's name was Uttara and the daughter's name was Uttarā. This Uttarā was taught dancing by Arjuna. When Arjuna was staying at Mahārāja Virāṭa's house as an ordinary dancing master, they did not know that he is Arjuna. Because the promise was for one year, they should remain incognito. If they are detected, then again for twelve years they will be banished.
