Gurudwara Tambu Sahib: Once Guru Nanak’s father, Mehta Kalu, gave him some money and sent him to Chuharkana, a market town, to purchase merchandise. But the Guru spent all the money in feeding a band of ascetics and came back fully satisfied with what he had done. Only as he neared Taiwandi, did he realise the possibility of his father’s displeasure and rebuke. Hesitant to face his father’s ire, he hid himself under a large van tree whose branches touched the ground making it look like a tent (tamhu in Purijabi) until discovered and taken home. A Gurudwara was established near the tree, about a furlong east of Janam Asthan during the Sikh Rule in Punjab. Its present building comprises a double-storey domed sanctum in the middle of a square hall which has architectural embellishments similar to those of Gurudwara Mal Ji Sahib but lacks the porches covering its door fronts.
A wild tree stands at this place. It is so old that its long branches touch the ground. It is a bit high at the centre. According to a Sikh legend, Guru Nanak rested for a while at this place, after returning from Chuharakana, performing the true business. The Guru had fed the hungry Sadhus with a sum of Rs.20/- obtained from his father. On knowing this, Mehta Kalu first felt annoyed with his son and afterwards brought him home.
On admonishing the son, the father received a reply that he had spent his money in the true business. On hearing of this incident, Raj Bular pleaded before Mehta Kalu by saying “Patwari Ji! Lest you chide the boy, let me make it clear to you that the whole City blessed by his grace and presence.” This shrine is situated at a distance of one Kilometer from Gurudwara Janam Asthan. Pilgrims feel it proud privilege to pay their homage.
