See what is Udaya Kumar's explanation about the symbol.
Mr. Udaya Kumar is from Tamil Nadu and not a Keralite.

CNN-IBN: Can you please explain to what it (the symbol) actually means?

D Udaya Kumar: I have given a lot of thought to this design. It is basically based on the letter 'ra' in Devnagri script. In that, I have just added a strikethrough line to represent Indian flag. And since I have incorporated the Devnagri script, it represents the Indianness of it because the top-line is quite unique and is not found in any other script. I have also tried to incorporate the Roman script 'R' within it for it to have an international appeal.
