How i broke a proud hindu boy and he wanted to convert

I am a married woman with two kids and still in my 30s. So i decided to join a online course of software development. I befriended a few people including a hindu . After some time i befriended a hindu man. So he was very religious. He is from a lower caste . I asked him what what is the concept of caste . He explained everything to me. And also explained the eater system and way of living of hindus. I then told him about jannah and way of living of muslims. So he wanted to learn more. After a week he was very much interested to learn more. I used to teach him 30 min everyday. I showed him the videos of zakir naik. He saw all of them. So he was very much convinced. I told him to follow the process of converting to a muslim. He said it's all right. I just wanted to see the impact of my dawah on a proud hindu. So all proud hindus can also be broken down.
