So, Ashu singlehandedly ( in every sense of the word) performs the surgery with Nidhi only assisting him. Of course, there are questions like why the CM's goonda son could not threaten any of the other senior docs in the conference room to assist Ashutosh. They were clearly surgeons, if not neurosurgeons. But then, that would not have served the purpose which is to establish Nidhi's professional credentials as also her commitment to her husband.
Mudra, I am quoting the same sloka that you did..
Karyeshu Dasi, Karaneshu Manthri;
Bhojeshu Mata, Shayaneshu Rambha;
Roopeshu lakshmi, Kshamayeshu Dharitri;
Satkarma Nari, Kuladharma Patni
According to the Hindu Mythology, the six criteria of an ideal wife:
Works like a servant, Advises like a minister, Feeds like a mother, makes love like a nymph, is as beautiful as Lakshmi, and forgiving like the earth.
Nidhi has already fulfilled all the other criteria. With this surgery, she has fulfilled the second one too!
