This English lady writer in an Introduction to Sikh Belief describes in an emotional manner the spiritual teachings of Guru Nanak Dev for the masses. She says that Sikh religion is such a simple path that if a person worships God with utter devotion, he can easily become one with God. According to the teachings of Guru Nanak Dev, God is the father of all and all human beings are brothers of each other. That is why in this religion all people without any discrimination of caste, colour, creed or sex can sit together and worship God.
