as per the show, I'ld like Guruma, to be that mother figure for Sadhna whom she missed from her childhood. A guru is said to be a parent for a disciple and since Guruma tied "Nara" in Sadhna's hand, Sadhna is a daughter cum disciple. It'd be great to see Sadhna excelling in this field and becoming independent with Guruma's guidance.
