With passage of time, the Sikhs felt the usefulness of maintaining the separate prominent identity. Like other religionists, they started feeling as 'more evolved that the Hindus'. So, for a Hindu, Sikh gurus are still part of their ancestory. Hindus consider Sikhism as another sect of their religion which has acquired distinct looks, dress code, rituals etc. It would not be a surprise, if down the ages you may start believing that SwamiNarayan sect is Non-Hindu, MurariBapu sect is Non-Hindu etc etc.
