"The show has brought me in touch with reality and taught me so much in the last two years that it can never be measured in money," he said on the "Aap ki Adalat" show.
"As creative persons we entertain people, but we also feel we have to contribute to our society by bringing about improvement in the social fabric and inculcate better values," he said.
"Two things are required to change India: one, all of us should change our attitude towards females, and two, we should not be self-centric and think about working in the larger interest."
The actor admits he is an emotional person and often cried while working on the "Satyamev Jayate" show.
"I wept several times while shooting for 'Satyamev Jayate' and the shooting had to be halted. It was terrible when common people narrated their woes.
"Even when I go abroad, I feel homesick and start weeping," he said.
The actor added that police had provided security to Mahvish, widow of Abdul Hakim, a resident of Bulandshahr in Uttar Pradesh who was apparently killed by his wife's family.
The couple had appeared in an episode of "Satymev Jayate" and spoken against honour killings.
Aamir said all five accused in the killing have been arrested and Mahvish, who is pregnant, was now getting police protection.
A doctor and a nurse have been assigned to take care of the widow, and if required she may be given treatment in a Delhi hospital, he added.
