“_Om Strípum_ the divine male and female”; the original androgyne or bisex being combined in the person of the first human being, Brahmá or Adam, and called the _Prakriti-purusha_ or _pradhána_ &c., in the Yoga and Puranic Systems. So says Manu also (I, 32). “The power became half male half female or nature active and passive, and divided itself in twain.” (Ibid). [Sidenote: 7. The cause and effect. कार्य कारणं ।] “_Om_ implies the two states of mundane existence, _viz_, the cause dynamic and the effect energy. The effect also is two fold, the gross and subtile.” (स्थूल सूक्ष्मञ्च). [Sidenote: 8. The Two Elements. स्थूल सूक्ष्मौ ।] The subtile elements (सूक्ष्मतन्मात्रं) and the gross elements (स्थूलभौतिकं) forming the Sthúla or gross body and the _linga Saríra_ or subtile body,—the two component parts of all living bodies. [Sidenote: 9. Knowledge & Ignorance. बिद्या बिद्ये ।] The two states of the soul, knowledge and ignorance (बिद्या अबिद्या) and the two states of knowledge; namely that which is known (बिज्ञात), and what is unknown (अबिज्ञात), corresponding with two others—the (ब्यक्ताब्यक्त) the manifest and unmanifest. [Sidenote: 10. The two states of Life. कर्म्म तथा ज्ञानकाण्डं ।] Knowledge and action or Jnána and Karman,—theory and practice, are the two inseparable conditions of life; the one leading to the other, which is the result of the former, and according to others its cause, in the celebrated dispute ज्ञान जन्य कर्म्म अथबा कर्म्मजं ज्ञानं between theorists and practitioners. [Sidenote: 11. Other Pairs.] In this way many other pairs are joined together forming as they were the two halves of the great circle of _Om_, and whether diametrically or obversely opposed or attached to each other, they form together, the same circle of which each of them is but an imperfect part or half. [Sidenote: 12. Geometry of _Om_.] [Sidenote: 13. Logical Use of _Om_.] Hence we see the mystery of the cypher of _Om_ to be no less wonderful and efficacious in the investigation of theological truths, than the great instrument of Euclid’s compass in the bisection and measurement of geometrical dimensions. And as the circle is latterly found to be made use of in the demonstration of propositions in Logic, how much must we wonder to reflect on the use and application of the sacred instrument of _Om_ by the ancient Rishis of India, to all things of the physical, intellectual and spiritual world (_Sarvamonkára eva_) as their common measure.
