Bhai Dipa was a dedicated Sikh of the time of Guru Arjan Sahib. He used to serve in Langar by cooking food and serving the visitors. He washed with warm water the feet of the Sikhs who used to come from distant lands to visit Guru Sahib. On nights, in winter, he would go round adjusting the quilts and blankets of the visitors. He would eat whatever was left. He was such a true example of devotion and Sewa (service) that Guru Sahib named him Dipak (lamp, which gives light to the others). Later, Guru Sahib appointed him a Masand.
