The concept of God in Sikhism is uncompromisingly monotheistic, as symbolized by "Ik Onkar" (one God), a central tenet of Sikh philosophy. The fundamental belief of Sikhism is that God exists, indescribable yet knowable and perceivable to anyone who is prepared to dedicate the time and energy to become perceptive to their persona.^{[citation needed]}

The Sikh gurus have described God in numerous ways in their hymns included in the Guru Granth Sahib, the holy scripture of Sikhism, but the oneness of the deity is consistently emphasized throughout. God is described in the Mool Mantar, the first passage in the Guru Granth Sahib, and the basic formula of the faith is:

Ik onkar satinam karta purakhu nirbhau nirvair akal murat ajuni saibhan gurprasad

One Universal Creator God, The Name Is Truth, Creative Being Personified, No Fear, No Hatred, Image Of

Guru Arjan, Nanak V, says, "God is beyond colour and form, yet His/Her presence is clearly visible" (GG, 74), and "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).
