16. The Belief (faith) of Sikhism

According to the belief of Sikhism, Sri Guru Granth Sahib ji is the embodiment and spiritual light of the Ten Masters. The Guru's are giving and will continue to give spiritual guidance and advice on well being to all those seeking this knowledge. Gurbani is the purest form of Divine knowledge from God. Sri Guru Granth Sahib ji is almighty god's (Waheguru) constant divine melody expressing his order and will (hukam). It depicts the obvious aspect of the formless creator who is beyond description or attributes of colour, caste, form, direction or measurement of any form. A constant stream of noble, godly virtues is flowing out of it and is calling upon every curious learner to acquire and utilize these pious qualities.  Sri Guru Granth Sahib ji is a treasure source of eternal peace and bliss, radiating its waves of peace, without discrimination, to all spiritual seekers alike. It contains the divine message and the command of God almighty on how to meet God, imbibe love for him, serene awe, crystalline divine knowledge, devotional reverence, devoted meditation, selfless service, benevolence, high moral character. Sri Guru Granth Sahib ji is a constant melodious stream of Holy poetic music. It is an invaluable treasure of spiritual bliss of the soul, and joy of merging with Almighty. It is the heart and extraordinary holy history of the dear Bhagats and the great Guru's. Whoever wants to study and analyze the inner feelings of the Bhagats and the Great Guru's, should read Sri Guru Granth Sahib ji with the deep love and devotion. Such a person will surely get glimpses of the Great Guru's and Bhagats. Sri Guru Granth Sahib ji is a clear vision of Almighty God himself. Knowledge pertaining to God is purely depicted through the egoless, pious hearts of Bhagats and Guru's, just as an image is formed in a clear mirror. Sri Guru Granth Sahib ji is the embodiment of our great Waheguru and pure pious knowledge regarding our lord. It does not carry even a bit of contamination of wealth. Gurbani purifies a learner's heart and soul from the effects of Maya (mammon). True Gurbani has the capacity to merge a mortal with the creator.

As Suhi Mahala third on page 754 :

Waaho! Waaho! Blessed, blessed is the Word of the Perfect Guru's Bani. It wells up and springs forth from the Perfect Guru, and merges into Truth. ||1||Pause||  

Whosoever recited this Gurbani achieved eternal spiritual stability and emancipation. The great Guru order as on page 1075 :

Those who meditate on it, are all emancipated;  they attain the eternal and unchanging home. ||8|| 

Gurbani is the form of Almighty Himself. Gurbani and the beloved lord are the same and vice-verse. It is also true as in Salok Mahala third page 515 :

Waaho! Waaho! is the Bani, the Word, of the Formless Lord. There is no other as great as He is.

For a Gursikh, the base of his life is Gurbani. As Page 759 :

I have the Support of the Word of the Guru's Bani. Attached to Gurbani, I survive. ||8||
