After thinking for sometime I guess I have managed to uncode the proper symbolism of that locket. Yes it is Sooraj's presence but it is much more than that. For understanding that locket in parachute better we first have to think why Sandhya wanted to do sky diving in the first place.
If you take the discussion she had with Sooraj it is to address her inner most fear. Now what is Sandhya's inner most fear. I mean the fear in her unconscious we can say as she has also not completely recognized it. But it exists. Her actions speak about that unconscious fear.
Now what is that unconscious fear. That fear is losing Sooraj. Sandhya is a teenager who suffered a deep trauma of unexpectedly losing her parents. Her parents had loved and cherished their daughter. They had supported her wishes , her dreams and were always there for her. But after their death every other relation has used her. Used her caring nature for their selfish gains.
If there was one person post her parents death who cherished her for what she is was Sooraj. He loved her when she didnt love him. He didnt made any demands to her. He was the person for whom her smile made his day. Sooraj was the person who bought alive the robot that Sandhya became post her parents death. It was his unconditional love that made the weathered plant that Sandhya was blossom again.
But even when he loved her Sandhya always feared losing him. His connect to Bhabo and family somehow made her understand that Sooraj was for family. If she doesnt take care of his family well she might end up losing him. And Bhabo has not spared a single occasion to drill this fear more and more into her mind. It was like if Bhabo is not kept happy Sooraj will not be happy.
This is the unconscious fear that makes Sandhya bend to all of Bhabo's unreasonable demands. yes she respects and loves Bhabo-Babasa as her own parents, but her unconscious always gives her the warning that how much ever she cares she is still DIL for Bhabo and at any point of time Bhabo has the power to take Sooraj from her.
All her struggles are infact to keep that one person who loves her unconditionally with her.
She not finding the locket at the time of jumping was the symbolism of her unconscious fear that Sooraj may not be there with her in situations when she needs him the most that means the risky situation and her trying to open that parachute is her struggle she need to take for being with Sooraj.
But once the parachute opens and the locket in the parachute was the symbolism that her worry was not needed. She didnt had to struggle or lose confidence in any situation. Even in sitautions which she thinks he will not be there and she needs to struggle he will be there. Sooraj cannot be seperated from Sandhya.
That locket in the parachute was the indication to Sandhya that no force in the universe including Bhabo can take Sooraj from her. He will be there with her always to hold her no matter what. 😃
