Each state had a "culture, (its) own thinking, own way of expression and food" and this diversity was India's strength and not a weakness, he told reporters here.

"The BJP and RSS are under the impression that one idea can be placed on top of India," Gandhi said, without elaborating.
Opposition leaders at a DMK event here yesterday raised these issues, Gandhi said, adding, "But India is not one idea; India is thousands of different ideas and this one idea of the RSS will never ever crush the thousands of ideas (of India)".
