Although the fourth is yang and firm, serving as the master of action and occupying the station of a great minister, yet because it is neither central nor correct and encounters a ruler who is dark, yielding, and weak, how could it bring about greatness and abundance?
Therefore it is called 'making his screen large.' A screen is that which encloses and conceals on all sides; enclosing on all sides makes it lack greatness, and concealing makes it lack brightness.
'At midday seeing the Dipper' means that at the very height of brightness, things on the contrary turn dim and dark. 'Yi lord' means an equal companion; because they correspond, the other is called lord.
The first and the fourth are both yang; the first resides at the beginning, so their virtues are identical, and they occupy positions of mutual resonance. Thus the first is its equal lord.
Occupying the seat of a great minister and gaining the assistance of a worthy below who shares the same virtue—how could such aid be small? Therefore it is auspicious.
If one of talent like the fourth gains the assistance of a worthy below, can he bring about greatness and abundance?
The answer is: when one below has someone in the Correct Position above to associate with, and one above has a worthy talent below to assist him, how could there be no benefit? Hence it is auspicious.
Yet bringing abundance to all under heaven requires certain conditions before it can be achieved: the fifth is yin and yielding, occupying the honored seat, yet the Zhen body lacks the image of being hollow-centered, yielding, compliant, and humbling itself before worthies; though there be many worthies below, what can be done?
For unless one is yang, firm, central, and correct, one cannot bring abundance to all under heaven.
