Explanation:

Although the Guru had settled down at Kartarpur, but he still took small tours within the radius of 100 to 200 miles around Kartarpur. He went to many places and preached his gospel of Nam. At many of these places, the people became Guru's followers and they set up Gurdwaras in his honor.

Many of his devotees left their homes and hearths to settle at Kartarpur and dedicate their lives to his mission.The Guru told the public on his arrival to kartarpur to indulge in labour and eat by doing hand work which is also called 'Dasa Nauha Di Kirat'.
Guru Nanak disciplined them and taught them a new lesson every day. Around this oasis of divine knowledge sat many seekers of Truth, eagerly drinking deep and picking pearls of wisdom to enrich their lives and to enrich humanity.
