Maan-samman...honor & self-respect...are as important to him as breathing is to stay alive. He holds these in high esteem...unnaturally so...because he has earned them. They were not handed out to him on a platter. He could have lost all his earnings all those years ago with one act of indiscretion...a phase of weakness in his life that he had deliberately blotted out from his existence later and moved on. Whatever may have been the reason, SP is not proud of the fact that momentarily he had lost control on himself. That one incident (or scare) turned him into a control freak. Because he lost control, he put the principles of life at risk...There was no way he was going to lose control again. So he proceeded to control all the extraneous elements ever since, including his family. As long as he had a hold on them, his own honor was intact. As long as they respected him unquestioningly and abided by his rules without deviating, his honor was intact. As long as he spoke and they only followed, his honor was intact. He thought his word was that infallible law that can never be broken, come what may.
Yet, all came crumbling down..and the armor of honor developed chinks the moment his wife passed away. Gradually SP is realizing all that maan-samman he enjoyed was in fact an illusion. He enjoyed it because that one person ensured he did...She was the silent, unseen support that upheld his honor. Her death exposed him to realities of relationships...realities of pseudo-honor...realities of ethics. He is seeing the realities of life as they are...only now...without any cover-ups or masks...and Radha is one such reality. The image of him and Radha in bed became a picture only now...a picture that had stayed a hazy negative for thirty years. Recall his first words after he jumped out of the bed, "What is happening? What are you all trying to do?" He acted as he would have if someone had caught him red-handed thirty years back in the same position...except it would have been real then, and no mirage. Hence, in a way this was a delayed reaction, yet very fresh.
Even if he wants to SP cannot bring himself to belittle Radha now, except for calling her "that woman." She is not only the reality his conscience had subdued all these years but she is also the woman who gave birth to the son on whom he depends the most and who has all the qualities that he wished in his own self. Unlike him, Yash doesn't have to assert to get respect, he gets it by just being himself. He sees a shadow of himself now in his son. SP knows Yash is an aberration to this society...his other family members are the face of society. Yash will never be judgmental where a parent is concerned, but the others follow the societal path. He should know...cause he was part of that judgmental group...still is!! In a way, this day he lost much more than what he lost a month back...his wife. He can learn to live with a life without Gayatri...How can he live a life sans his honor? Now he knows what Radha would have gone through when he stripped her of her honor. He did to Radha thirty years ago what his family is doing to him now: denying him the life of honor and self-respect he so revered.
