Sanskrit. "Absolute Necessity" (to overcome the inertia of the human organism). One of the four Yogas mentioned in the Upanisads (Mantra, Raja, Laya). Symbolically, it is the "union" (Yoga) of the "Sun" (Ha) with the "Moon," (Tha) and thus dissolving the polar opposites through the interface of Mind-Body.
