Mumbai: Megastar Amitabh Bachchan feels that divinity is a belief which we should not try to speak about in public as it's personal. “Divinity was ever personal with us. Our faith and our prayers and our temples were and are within the house. There is no need to make them public or to bring it to the masses. "It is a belief, and beliefs are within and personal,” Amitabh, who has sung a devotional song along with singer Kailash Kher for the Kedarnath Temple, wrote on his blog on Thursday. The “Piku” star, meanwhile, also shared that he has lent his voice for the Hindi version of Hollywood filmmaker Steven Spielberg's “The BFG”. “Early mornings begin with a gentle giant and a little kid. 'The BFG' of Steven Spielberg, being dubbed in Hindi, and they chose me as the giant’s voice. It is quite remarkable to see the advancement of technology in the film. And of course in the digital virtual world,” Amitabh wrote. The film is based on the 1982 novel of the same name by Roald Dahl.
