Bhai Kulla Jhanjia was a devout Sikh of the time of Guru Arjan Sahib. Once he, accompanied by Bhai Bhulla Jhanjhi and Bhai Bhagirath, went to make obeisance to Guru Sahib. They learnt the lesson of becoming a Gurmukh (one who lives according to the teaching of Guru) from Guru Sahib and lived their life accordingly. Also see: Bhulla Jhanjhi, Bhagirath.
