Every action of Sdahna, including singing a mother's lori, to feeding her baby for the last time and then giving her baby to Ragini, putting Alekh as well as baby to sleep, telling Mamaji to teach Khushi all "good sanskars" and finally leaving Khushi in Ragini's lap and calling Ragini Khushi's "MasiMA"...everything was so meaningful and pointing to Sadhna's end...
Creatives should not bring back Sadhna and make her character an average one...They have consistently shown Sadhna's character as an epitome of goodness and selflessness. Her every action was so much above average always, that viewers sometime felt "why did she do that ?"....Her character has reached such a dimension that in her presence, everyone's goodness seems to be pale.
Sadhna has to stay alive, but in the minds, in the hearts, in the good acts of her beloved. If Sadhna can come back, she can only do as a 'parchhai" and that too in the form of Khushi...Good souls only live till the time they are needed...Sadhna has done enough good and she has borne enough from outsiders as well as her own people.
This is my analysis for the character "Sadhna", not Sara Khan....but thanks to Sara, who put life to the character of Sadhna...
