In the words of Bhai Gurdas ji, a great scholar of the Guru’s time, “In the word is the Guru, and the Guru is in the word (shabad). In other words, the human body was not the Guru, but the light of the word (shabad) within the heart was their real personality.”
When the human mind dives deeper and deeper into the Guru’s word, all mental impurities depart and the wisdom of the Guru permeates the human soul. Thereby the devotee attains the divine light and wisdom which leads him to contemplate and meditate on God’s name (naam). In the light of the above realities, the Sikh religion makes the holy Granth the living master of the Sikh Panth.
Before he died, Guru Gobind Singh, the tenth Guru, conferred the Guruship to the [Adi Granth]. He then delivered a self-composed hymn:
Agya bhai Akal ki tabhi chalayo Panth. Sabh Sikhan ko hukam hai Guru manyo Granth. Guru Granth Ji manyo pargat Guran ki deh.
Jo Prabh ko milbo chahe khoj shabad mein le. Raj karega Khalsa aqi rahei na koe ,Khwar hoe sabh milange bache sharan jo hoe.”
Translation:
Under orders of the Immortal Being, the Panth was created. All Sikhs are enjoined to accept the Granth as their Guru. Consider the Guru Granth as an embodiment of the Gurus.Those who want to meet God, can find Him in its hymns. The pure shall rule, and the impure will be no more, Those separated will unite and all the devotees of the Guru shall be saved.
