Narendra Modi chose to ignore Prime Minister Manmohan Singh's sharp attack on him on Friday in which he was accused of "presiding over mass massacre of innocent citizens on streets of Ahmedabad" in 2002.
At an event organised by Baba Ramdev, Modi hardly touched on Singh's onslaught against him except for a tangential reference to allegations levelled against him.
"When these days people level baseless allegations at me, I look back (at my life) and think how great this country is and how great its people are who have lifted a 'chaiwala' (tea-seller) on their shoulders... There is no place for disappointment for a man who has lived this life," he said.
Singh had at a press conference said that it would be "disastrous" for the country if Modi were to become Prime Minister.
The Prime Minister was, however, at the receiving end of the attack by Leader of Opposition in Rajya Sabha Arun Jaitley.
Jaitley, who spoke before Modi at the same event, said the one lesson they could learn from Singh's tenure was that the post of PM is not a mere "employment".
"It is not an employment. History won't judge you on how many years you served but what you did for the country," he said in his dig at Singh, who had hoped history would be kinder to him than media and opposition.
He said a contest seemed to be on between Ramdev and Modi as to who is the more victimised man for UPA government's attempts to cook up false cases against them.
"There won't be probably any kind of probe which has not been ordered against Modi. After 10-12 years, he has come out unscathed," Jailtey said.
Taking on Singh for his remarks that he considered Indo-US nuclear treaty as a high point of his tenure, Jaitley said it was rather a "most shameful" moment because MPs were "bribed" to ratify the agreement in Parliament.
Ramdev took objections to Singh's attack on Modi, asking if the PM had no trust in the judicial system which has given a clean chit to BJP's Prime Ministerial candidate.
