He also joined hands with Bhai Paro in inaugurating, with the Guru`s approval, an annual fair at Goindval to celebrate Baisakhi. Lastly, when Emperor Akbar met Guru Amar Das and wanted to make an endowment for Guru ka Larigar, an offer politely turned down by the Guru, it was at Bhai Ballu`s suggestion that the emperor made a gift of some land to the Guru`s daughter, Bibi Bhani. It was on this site that the holy city of Amritsar was laid out by the third Guru`s successor, Guru Ram Das, Nanak IV.
