Nirgun and Sargun is terminology used within Sikhism to refer to the ineffable (nirgun) and the manifest (sargun) nature of God.
[1] There is no dichotomy in the nirgun and sargun nature of God,[2] as there only One (Ik Onkar).
"Before creation, God existed all alone as Nirgun in a state of Sunn Samadhi, deep meditation, as says Guru Nanak.
"Then God willed, created the universe, and diffused into nature as Sargun.
[6] The Sikh view of the dual nature of Absolute God runs parallel to Shankara's Vedic (Saguna and Nirguna) Brahman conception, as well as the tradition of Indian philosophy in general.
