In fact, he was having simple vegetarian food and wore ordinary clothes. To immerse himself into the Rajkumar's character, he started doing meditation and prayed the late Kannada superstar to help him.
He further explains, “Before every shot, I prayed to him and in one of the scenes, in which I am taking leave of Veerappan, I felt the spirit of Dr Rajkumar come into me and, at that moment, I wasn"t Suresh Oberoi."
