During his longest tour called first Udasi Guru Nanak yisited Hardwar, a pilgrimage centre of the Hindus. It was believed that a dip in the holy Ganges would absolve the bather of all his sins. The Guru himself entered the river at Kushwan Ghat and started splashing water with his left hand towards the west, while other pilgrims were splashing water towards east. When questioned by others ,the Guru informed them that he was directing water to his thirsty fields in Punjab. The priests laughed and asked him how water could reach his crops situated 460 km away. Guru Nanak politely told them if water sent by him could not reach his fields in Punjab, how could it reach their ancestors in the heaven. The Guru's reply startled the people. At first they were a bit perplexed but later began to realise the truth in the Guru's statement.
