Spoken by Guru Nanak when he became Enlightened. Note: the word "he" in that language of that place and time is not to be construed as the same type of "he" as in Judaeo-Christianity. In the Mool Mantra, "he" refers to the Impersonal Absolute that is (in a way, personal also); but not to be taken literally as a Personality such as Yahweh.
