Creatives just immortalised the creation "Sadhna" and labelled her synonymous with "Selflessness".
The creatives might have killed Sadhna, I do not want to go into discussion "why they killed". Its a story and being a fan of Bidaai and more so of Sadhna, I feel they maintained the selflessness of Sadhna from beginning to end . They tried to establish and prove Sadhna's love for her jiji more than anything else from the beginning and till the end, they showed how "she took the death of her jiji onto herself". She had premonitions and she somehow could feel the connection between "death and the bracelet"...and she took away that bracelet from her and in the temple, she asked that whatever is approaching her jiji, should fall on her...
Bidaai's main concept was whether "fair skinned girls indeed luckier"? It revolved around two sisters and from the beginning, the story showed Sadhna's selfless sacrifices for Ragini, Sadhna like a mom feeling every pain of Ragini and today, she ended also with that thought "that my jiji be safe, and let me die my jiji's death"...
Many days back, Zee had made a post "Behen ho to aise"...
She died to save a little girl whom she never knew also...I think today I'll go a little more and say "Insaan ho to aise"..again and again...
