putranam duhitrnam ca
darair varais tat-sadrsaih
Narada saw Lord Krsna engaged in getting His sons and daughters married to suitable brides and bridegrooms at the appropriate time, and the marriage ceremonies were being performed with great pomp.
This translation is based on Srila Prabhupada’s Krsna.
The word kale here means that Krsna arranged for His sons and daughters to be married when each of them reached the proper age.
