They sent one dyuti, messenger, "You go and see where is this Krsna!" So the dyuti went out and on the way met Saibya, Candravali's companion sakhi. Saibya told her that Krsna is in Candravali's kunja. So that dyuti came back and reported it to Lalita and Visakha. "Krsna is in Candravali's kunja." So Visakha became very angry. Lalita is a bit less inflammed and Visakha was now very serious. They reported this to Radharani. Radharani became sulky. Radha's optimism turned to pessimism as her mood became heated and reached its peak.

It is interesting to note that during Sri Krsna's Mathura\Dvaraka pastimes Rukmini was provided great assistance and advice from Saibya.
One of Krsna's Queens named Mitravinda was also addressed as Saibya, the descendant of Sibi. SB 10. 41-42
Candravali is none other than Rukmini and her dearest confidant is Saibya. -AJD
