Sri Guru Ram Das ji are known to be the Chauthi Patshahi or the Fourth Guru as well as Guru who established the city of Amritsar. Sri Guru Ramdas ji kept alive the tradition of first three Gurus. Sri Guru Ramdas ji were Guru for a short period. After obtaining land for the purpose, he founded the town of Ramdaspur (later Amritsar) which continues to be the centre of Sikhism till today. He dug a tank which became the principal place of pilgrimage. Traders and artisans were invited to settle at the town so that its growth could be rapid. In due course it became the largest commercial centre in northern India. Phrase came to be associated with the tank dug at Amritsar which was "Ramdas Sarovar Nahate, Sab uttre paap kamate", "I bath in the tank of Ramdas and all my sins were washed away" . It was a landmark in the life of the community, because the Guru established a central place that was quite distinct from that of the Hindus and the Muslims. Since then Amritsar is for the Sikhs what Mecca is for the Muslims. All this indicates that the Guru had a distinct sense of his mission and did everything to establish it as a separate religious system and entity.
