Explanation:

In his first Udasi (travel), Guru Nanak covered east of India and returned home after spending about six years. He started from Sultanpur in 1500 and went to his village Talwandi to meet and inform his parents about his long journey. The old parents wanted comfort and protection from their young son in their old age and so they preferred it for him not to go. However, Guru ji convinced them and also there were thousands and thousands others waiting for the Divine Master for comfort, love and salvation. The Guru, therefore, told his parents,"There is a call from Heaven, I must go and I ask for your blessing." Finally they agreed and Guru ji set off on the first of his four journeys.
