"In Ayodhya, Narada and Ram were talking one day. Narada said, 'Ravana is enjoying his time on earth, and you are here in Ayodhya. When will you go and kill him, which is the reason for your embodiment?' Ram replied, ' Let him enjoy all he wants, for as his enjoyments become satisfied the time will arrive for effectively dispatching him.'"
The state of liberation that all seek after, consciously or unconsciously, will arrive at the proper time, after worldly desires are met and filled.
