The guru is the one who guides his or her disciple to become a jivanmukta, liberated soul that achieves salvation in his or her lifetime through God-realization.
Guru Nanak, the first guru of Sikhism, was opposed to the caste system prevalent at his time in India and accepted Hindus, Muslims and people from other religions as disciples.
GuruArjan Dev was the youngest son of Guru Ram Das and Mata Bhani.
In 1579 GuruArjan was eventually married to Ganga Devi daughter of Krishan Chand in 1579.
GuruArjan Dev exclaimed; "My faith is for the people of all castes and all creeds from whichever direction they come and to whichever direction they bow." To help raise money for these monumental public works projects, the Guru declared that all Sikhs should donate 1/10th of their earnings to charity.
