`Purakh` as a linguistic symbol derives from the Sanskrit purusa (man), invariably employed in the masculine gender.In the Vedic literature, the term also stands for the world, indicating the entirety of universal existence. In the Indian systems of Sarikhya and Yoga, Purusa, as one of the two cardinal metaphysical principles, stands for spirituality or simply consciousness, which exerts influence on Prakriti (Nature) that is physical in its makeup. The core of purusa, therefore, is consciousness, denoted by chit in the Satchitanand conception of the Absolute.
This connotation of the term invests `Purakh` with spirituality, signifying the Divine Person. In conjunction with akal, the expression as a whole means the Everlasting Divine Person (God), in the Sikh tradition and literature. `Akal Purakhu* as a single composite term appears only once in the Guru Granth Sahib (GG, 1038). We also come across the term in Guru Ram Das, Gauri Purabi, Karhale (GG, 235), but in the inverse form as PurakhuAkali.
However, the Dasam Granth compositions of Guru Gobind Singh often employ Akal Purakh as a substitute for God, the Eternal Being. Akal being a cardinal and central concept in Sikhism, its use alongside of Purakh, accords it a distinct theological status. See AKAL
