This shall be your seva, i.e. service.” Bhai Bula adhered to the Guru`s direction and became a favourite Sikh of his. According to Giani Gian Singh, Twarikh Guru Khalsa, Bhai Bula was one of those who, led by Bhai Jetha (later Guru Ram Das), went to the Mughal court at Lahore in the time of Guru Amar Das when complaints had been laid before Emperor Akbar about the Guru`s teaching refuting the Hindus` traditional belief and practices. Bhai Jetha and his companions explained to the Emperor how Guru Nanak`s message was meant for all, making no distinction between the Hindu and the Muslim.
