The 42-year-old admits she regularly goes to temple to “chant and pray and celebrate” with her three children and husband cameraman Daniel Moder, reports dailymail.co.uk.
She said: "I'm definitely a practising Hindu. Golly, I've been so spoiled with my friends and family in this life. Next time I want to be just something quiet and supporting."
In the film, Roberts plays a woman hoping to find herself through Hindu spirituality.
The actress caused controversy in India last September when local Hindus were barred from celebrating an important religious festival while she shot scenes for the film in their temple on the outskirts of New Delhi.
Villagers hoping to mark the beginning of Navratri, nine days of worship of their Goddess Durga, at Ashram Hari Mandir in Haryana, found their temple sealed by Roberts's vast security team of 350 guards, bulletproof cars and a helicopter.
“Eat, Pray, Love” is a big screen adaptation of the bestselling memoir of the same name by Elizabeth Gilbert.
