ਗੁਰੂ ਗ੍ਰੰਥ ਜੀ ਮਾਨੀਓ ਪ੍ਰਗਟ ਗੁਰਾਂ ਕੀ ਦੇਹ ॥
Accept Guru Granth Sahib as Almighty Guru.

We can thus see that the same Divine-spirit of God that was available, for spiritual guidance, to the human race on earth, in the body of Guru Nanak Sahib and his commissioned successors, had finally come to manifest in Guru Granth Sahib making the latter everlasting, all powerful and perfect spiritual leader (Guru) for the entire human race on earth for all time to come. It is the same super Soul, giving the same message of God which Guru Nanak had spread, but in the form of Holy Hymns – a changed form from the previous human form. the change is of the exterior only.

ਜੋਤਿ ਓਹਾ ਜੁਗਤਿ ਸਾਇ ਸਹਿ ਕਾਇਆ ਫੇਰਿ ਪਲਟੀਐ ॥

{966}

2. The Holy Hymns of God (ਗੁਰਬਾਣੀ) which collectively constitute the Guru Granth Sahib, descended from Almighty for the guidance of the entire humanity, through Guru Nanak Sahib, his successors and other saints on whom Guru Nanak had bestowed his full benevolence. Holy Hymns were compiled together by Guru Arjan Dev Ji (the 5th Guru Nanak) in the shape of Adi Granth Sahib. The 10th Guru, Guru Gobind Singh Sahib, before parting from his human body, had incarnated the Divine spirit in the Granth Sahib, and prefixed the word ‘Guru’ to Him and addressed Him as Guru Granth Sahib, from then on, and said:

ਗੁਰੂ ਗ੍ਰੰਥ ਜੀ ਮਾਨੀਓ ਪ੍ਰਗਟ ਗੁਰਾਂ ਕੀ ਦੇਹ ॥

ਜੋ ਪ੍ਰਭ ਕੋ ਮਿਲਬੋ ਚਹੈ ਖੋਜ ਸਬਦ ਮਹਿ ਲੇਹ ॥
Accept Guru Granth as Almighty Guru for all ages henceforth.

Whosoever is desirous of seeking communion with God, let him search through the hymns of Guru Granth Sahib.

God’s message was preached by the Gurus to the humanity only through God’s Holy Hymns, and so also by the Sikh priests subsequently.

3. Thus we have, by now, ample conviction to say that Guru Granth Sahib is the only right source of spiritual guidance and Divine Light, available to the human race on earth as destined by God. Let us now see what these, Holy Hymns of God reveal about the role of the true Guru (ਸਤਿਗੁਰੂ) – an Almighty Guru (ਪੁਰਾ ਗੁਰੂ). Here we shall cite only a few Holy Hymns of God to keep the volume of this write-up from getting bulky. Guru means “The One”, who is in tune with God and is, thus, competent to dispel internal darkness (delusion) by kindling spiritual light, and elevate our souls to the level of the Supreme Soul (God) to help merge in Him.
