豫卦 (Delight Gua) is formed from a upper zhen (震) Trigram and a lower Kun (坤) Trigram. All the Yao (爻) are Yin (阴) with the exception of the Fourth Yao (第四爻), which carries a powerful Yang (阳) influence but not in the correct position of power. An analogy of a man visiting a brothel, surrounded by women in the state of Delight.
In this formation, it is ‘believed’ that the Yin Yao (阴爻) will act in obedience to the single Yang Yao (阳爻). But, being the only Yang Yao (阳爻) in this Gua, this means the person is surrounded by danger (坎), looking at 3rd, 4th and 5th Yao (第三，四，五爻) this makes up the formation of Kan Trigram (坎卦), although in Delight, one is also treading precariously in danger waters.
Another way to look at his Gua (卦), is the high rising Yang Yao (阳爻) is also an indication of one’s peaking in terms of performance and influence, what comes next is decline and decay “物极必反” and “乐极生悲”.
