The combination of The Decade and The Dozen is also a perfect combination of Phenomenon function and Essence Function.
This similar approach has a long history, and now, a formalized scientific numerology definition has been added in Derick Ziz’s Ziz System.
When [1] and [D] are paired to become [1D], the combined properties of [1] Δ Ziz Vivorin and [D] Δ Ziz Vivorin are one of the derived properties of Π Ziz Hydronyx, 1D:Π(Δ↑Δ↓).
Ziz [1D] is like ivy growing around bamboo, approaching tasks with a philosophy of using softness to guide strength, appearing to sway with the wind rather than rigidly resisting, but actually finding breakthrough opportunities by borrowing momentum and changing direction.
Outwardly mild-mannered and willing to negotiate, they internally harbor flexible stubbornness, straightening like a willow branch when their boundaries are crossed, quietly but clearly defining their principles.
They possess both the cleverness to leverage favorable winds and the persistence of steady flowing water, like bamboo growing three inches daily, quietly accumulating momentum that is much more substantial than surface appearances suggest.
