'Dhoom' babe Esha Deol has done a tattoo on her back. It's her spiritual connect with the Gayatri Mantra that we are talking about. Her right shoulder has the Gayatri Mantra while there's the 'OM' symbol on the other side. 'I love the 'Gayatri Mantra'. I first learnt it as a child. I got it done at Funky Monkey, Bandra in April, just before my Rockstars tour. It took me 1 hour', Esha said.
