Do you know that having two passport is illegal. Where have you been?
"The Indian Citizenship Act, 1955, does not allow dual citizenship. Holding Indian Passport / acquiring Indian Passport / travelling on Indian passport after acquisition of foreign citizenship constitutes an offence under the Indian Passport Act, 1967, and attracts penalties."
"Under the Indian law, Persons of Indian Origin who have acquired foreign Nationality are required to surrender their Indian passports to the nearest Indian Mission/Post immediately after acquisition of foreign citizenship."
If you travel with your Indian passport and if they find it out then be ready to face the music. Carry plenty of cash to bribe those assholes at immigration. If you are landing at Mumbai then good luck. Those c***suckers are waiting for "Murgas" like you to make extras. Same at Delhi. You may get away at Bangalore.
Moral of story is surrender it ASAP and avoid all troubles. You don't want to mess with these Indian bloodsuckers. They will make your life hell. Have been there seen that. My personal experience.
