Prime Minister Narendra Modi said welcome greetings in six Indian languages as he unveiled the logo for India's G20 presidency, based on the lotus flower; and its theme, based on universality, and the website, g20.in, on Tuesday. "In Indian culture, both, the goddesses of knowledge and prosperity are seated on a lotus," he said, referring to Hindu goddesses Saraswati and Lakshmi. The seven petals of the lotus in the logo, he said, represent the seven continents. It ties in with the theme of 'Vasudhaiva Kutumbakam' or 'One Earth, One Family, One Future', he added.
