Bhai Gurdas was a contemporary of the fourth, fifth and sixth Gurus and was acquainted with them and their contemporaries, especially Bhai Buddha, an aged Sikh who had survived from the time of Guru Nanak. The tenets of Sikh religion are given in Bhai Gurdas’s Vars. There are forty Vars in number and each is divided in varying number of pauries (stanzas) and each pauri contains from five to ten lines.
One morning the Guru went to Bhai Gurdas whose end was now approaching. He begged pardon for any sins he might have committed. The Guru replied,” I thank thee, Bhai Gurdas, for having assisted in laying out the road of the Sikh faith. Among the Gurus’ Sikhs thy name shall be immortal.” Having heard this Bhai Gurdas meditated on God and drew a sheet over him and closed his eyes in eternal sleep on Friday the fifth day of the light half of Bhadon, Sambat 1686 (1629 A.D.). After performing the last rites he returned to Amritsar. It should also be noted that “Bhai Gurdas ji dian waran” is called as the key to the sikhism.
