Mohandas himself had heard that many well-to-do people had started eating meat, So he tried meat. He did not like the taste of meat but as time went on he started to like meat currier. Whenever Mohandas had a meat meal outside, he had to give his mother some excuse for not eating his dinner. He knew that his parents would not forgive him if they knew he had eaten meat. He was not against eating meat then, but he was against telling a lie to his mother. This feeling was gnawing at his heart and finally he decided not to touch meat again.
