Guru Nanak prefixed the numeral one (ik) to it, making it Ik Oankar or Ek Oankar to stress God's oneness. God is named and known only through his Own immanent nature. The only name which can be said to truly fit God's transcendent state is SatNam ( Sat Sanskrit, Truth), the changeless and timeless Reality. God is transcendent and all-pervasive at the same time. Transcendence and immanence are two aspects of the same single Supreme Reality. The Reality is immanent in the entire creation, but the creation as a whole fails to contain God fully. 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).
