They don't believe just in the Hindu concept of meditation. That's looking inward. They also believe that the goal of man is not just to use his spiritual life but to live his secular life as well. The deeds that you do on earth. And I might have mentioned this before. They don't believe in conversion. The purpose of their life isn't to convert other people to Sikhism but rather to go out and to help other people and to find ways of equality and social justice.
