Meaning
Guru Nanak's opening words in the Guru Granth Sahib run: one reality, whose name is truth, the creative being, without fear, without hatred, timeless in form, unborn, self existent, known by the Guru's grace. Each term denies a limit rather than describing a shape. Sikhs read it as the whole teaching compressed into a line, with everything after it an unfolding of these words.
