In a no-holds-barred attack, Congress said Modi needs "very serious counselling".
Congress senior spokesman Anand Sharma also sought an independent inquiry into organisation of public events for the PM during his foreign tours and the source of "millions of dollars" required for hosting them.
Hitting back, BJP said Congress has become the voice of "untruth, malice and utter frustration" and wondered if it had become "trapped in an inept leadership".
"In our country it doesn't take much for allegations to come up against politicians... Someone made 50 crores, someone's son made 250 crores, (someone's) daughter made 500 crores, (someone's) damaad (son-in-law) made 1000 crores," Modi said.
Referring to Modi getting emotional and breaking down while talking about his mother, the Congress spokesman said, "true to his characteristic style, the PM once again engaged in theatrics, emotion and drama, making boastful claims".
If Modi considered himself a powerful leader, then why has he not ensured that his mother stayed with him.
"Is it not the duty of a son to look after the well-being of his mother," he said recalling that Modi was chief minister of Gujarat for 12 years and said then and even now he has not brought her to his home.
"The Prime Minister is misusing his official visits abroad and we demand an independent inquiry (into the rallies)...With 100s of millions of dollars spent in their organisation with activists of the RSS and others going months ahead for preparations", he said.
