See now our Sphinx, with what Subtility and Art is She made Whole! Here is thy Light, the Lion, the Necessity of thy Nature, fortified by thy Life, the Bull, the Power of Works, and guided by thy Liberty, the Man, the Wit to adapt Action to Environment. These are three Virtues in One, necessary to all proper Motion, as I may say in a Figure, the Lust of the Archer, the propulsive Force of his Arm, and the equilibrating and directing Control of his Eye. Of these three if one fail, the Mark is not hit. But hold! Is not a Fourth Element essential in the Work? Yea, soothly, all were vain without the Engine, Arrow and Bow. This Engine is thy Body, possessed by thee and used by thee for thy Work, yet not Part of thee, even as are his Weapons to this Archer in my Similitude. Thus is thy Dragon to be cherished of thy Lion, but if thou lack Energy and Endurance of thy Bull, thy Tools lie idle, and if Cunning and Intelligence, with Experience also of thy Man, thy Shaft flieth crooked. So then, o my Son, do thou perfect thyself in these Four Powers, and that with Equity.
