"The origins of Sikhism lie in the teachings of Guru Nanak and his successors. The essence of Sikh teaching is summed up by Nanak in these words: ‘Realisation of Truth is higher than all else. Higher still is truthful living.’ Sikh teaching emphasizes the principle of equality of all humans and rejects discrimination on the basis of caste, creed, and gender.
"Sikhism is a monotheistic and a revealed religion. In Sikhism, God is shapeless, timeless, and sightless. The beginning of the first composition of Sikh scripture is the figure “1"—signifying the universality of God. It states that God is omnipresent and infinite. Sikhs believe that before creation, all that existed was God and Its hukam (will or order). When God willed, the entire cosmos was created. From these beginnings, God nurtured ‘enticement and attachment’ to māyā, or the human perception of reality.
"While a full understanding of God is beyond human beings, Nanak described God as not wholly unknowable. God is omnipresent (sarav viāpak) in all creation and visible everywhere to the spiritually awakened. Nanak stressed that God must be seen from “the inward eye”, or the “heart”, of a human being: devotees must meditate to progress towards enlightenment. Guru Nanak Dev emphasized the revelation through meditation, as its rigorous application permits the existence of communication between God and human beings.
"God has no gender in Sikhism, (though translations may incorrectly present a male God); indeed Sikhism teaches that God is "Nirankar" [Niran meaning "without" and kar meaning "form", hence "without form"].
"In addition, Nanak wrote that there are many worlds on which God has created life"
