Dasarathas dilema

Of the four sons Dasarathas love fo r Rama is very much.So he wanted to make him the king.He got acknowledge ment from the people.He did not invite JANAKA And Kekaya KINGS.If Kekaya king came and enquired about promise he made at the time of marriage, he can not answer. If Janaka comes and questions about his son in law was not made the king as he was the eldest he could not answer.So he abstained from inviting both of them.

He was afraid that Kekaya king might have told this secret to Bharatha.What if Bharatha creates trouble in this regard?So he felt it would be better if Rama was made king before his arrival.Then he can not do anything.

Vasishata was kings Raja purohith. So he would definitely be knowing about this Rajya sulkamu.If Dasaratha asked him to fix an auspicious date for the function, Vasishta might object and recall about his promise.He might request Dasaratha to wait till Bharatha came and then proceed. By that time it might be too late.So Dasaratha himself fixed the date. Once it is confirmed by the king Vasishta would not interfear.
