The XSE Key, when grasped, enables an immediate metaphorical removal or detachment from the moment physically, mentally, and emotionally/spiritually in order to empower the systems engineer to enhance system strength through application of optimal choices (XSE’s Y Axiom), increasing the potential for achievement. The key “unlocks” XSE’s 2FA to then pass into the XSE Vantage Point for an all-encompassing view of systems (from the SOI to the SOC, including the systems engineer) and the integration with other systems. From this Astronomical zone, a systems engineer, free of all pre-conceived notions (physical, mental, emotional, etc.) and limitations, is positioned for universal advancement and unlimited exploration of what physicists and scientists have introduced as the fourth dimension. From the XSE Vantage Point, a systems engineer or sustaining systems engineer is empowered to leverage the X Axiom (Using critical and creative thinking augments intelligence) and the Y Axiom (Seeking authentic and ultimate sources maximizes freedom) for system optimization.
