For the Sikhs, the Creation is His pleasure and play "When the showman beat His drum, the whole creation came out to witness the show and when He puts aside his disguise, He rejoices in His original solitude" (GG, 174, 291, 655, 736). To quote Guru Arjan again, "The created cannot have a measure of the Creator what He wills, O Nanak, happens" (GG, 285). What is the Creator's purpose in creating the universe? It is not for man to enquire or judge the purpose of His Creator. He is the Creator, Sustainer and the Destroyer. Creation is "His/Her sport which He witnesses, and when He rolls up the sport, He is His/Her sole Self again" (GG, 292). Included in Sach Khand (Realm of Truth), the figurative abode of God, there are countless regions and universes" (GG, 8). Even at one time "there are hundreds of thousands of skies and nether regions" (GG, 5). “Many times He expands Himself/Herself into such worlds but He ever remains the same One Ekankar" (GG, 276). God is immanent in the created world, but is not limited by it. The latter exists and is contained in Him/Her and not vice versa. But God is not identical with the universe. It is not "maya" or illusion but is real (sat) because, as say Guru Arjan, “True is He and true is His/Her creation all has emanated from God Himself” (GG 294). He created the spatial-temporal universe not from some pre-existing physical element, but from His/Her own Self. As says Guru Tegh Bahadur, Nanak IX, "He has himself spread out His/Her Own "maya" (worldly illusion) which He oversees many different forms He assumes in many colours, yet He stays independent of all" (GG, 537). The Reality is immanent in the entire creation, but the creation as a whole fails to contain GOD fully. Transcendence and immanence are two aspects of the same single Supreme Reality. GOD is transcendent and all-pervasive at the same time. The only name which can be said to truly fit GOD's transcendent state is Sat or Satnam (Sanskrit meaning TRUTH ), the changeless and timeless Reality. GOD is named and known only through GOD's Own immanent nature. Guru Nanak prefixed the numeral one (ik) to it making it "Ik Oankar" or "Ekankar" to stress GOD's oneness.

One Universal Creator God,The Name Is Truth,Creative Being Personified,No Fear,No Hatred,Image Of Ik oankar satinamu karta purakhu nirbhau nirvairu akal murati ajuni saibhan gurprasadi Briefly, God for the Sikhs as described in the Mool Mantar, the first passage in the Guru Granth Sahib and the basic formula of the faith is: The Gurus have described God in numerous ways in their hymns included in the Guru Granth Sahib, but the oneness of the deity is consistently emphasized throughout.
Sikhism as a religion is uncompromisingly monotheistic. Says Guru Nanak, budhi pathi na paiai bahu chaturaiai bhai milai mani bhane which translates to "He/She is not accessible through intellect, or through mere scholarship or cleverness at argument He/She is met, when He/She pleases, through devotion" (GG, 436). In any case, knowledge of the ultimate Reality is not a matter for reason it comes by revelation of the ultimate reality through "nadir" or grace and by "anubhava" or mystical experience. Guru Arjan, Nanak V, says, "'God is beyond colour and form, yet His/Her presence is clearly visible"' (GG, 74), and again, '"Nanak's Lord transcends the world as well as the scriptures of the east and the west, and yet He/She is clearly manifest'" (GG, 397). The never spoke about proofs of the existence of God: For them He/She(God in Sikhism does not have a gender) is too real and obvious to need any logical proof. The fundamental belief of Sikhism is that God exists, not merely as an idea but as a Real Entity, indescribable yet knowable and perceivable to anyone who is prepared to dedicate the time and energy to become perceptive to His/Her persona.
