"The teachings by Lord Krishna in Bhagwad Gita are life and soul for me. They are the absolute foundation and motivation for the actions and the work and everything that I am trying to do with my life," she said during a discussion on 'The Future of Indo-US Relationships' organised by the India Foundation.

"It's not just the political leaders who are charged with this responsibility but each of us with our own lives," she said.
Gabbard, who took her oath as a US Congresswoman on the Bhagwad Gita, said that the text would remain relevant regardless of time and age.
