奇門遁甲定局不能依後天卦數的理由 近道
(一).目前流傳最廣的奇門遁甲時局,係採十時一局法,如陽局冬至用坎一卦數上元一,中元七,下元四,小寒上中下元二八五,大寒上中下元三九六,立春用艮八卦數上元八,中元五,下元二,雨水上中下元九三六,驚蟄上中下元一七四...,其依據為古歌云:冬至小寒大寒,天地人元一二三;夏至小暑大暑,天地人元九八七.顯然將一節三氣誤解成天地人三元,冬至(天)上中下元用一七四,小寒(地)上中下元用二八五,大寒(人)上中下元用三九六,立春上元則跳至陽八局,致每氣局數不能銜接.

(二).冬至後一陽生,配卦為地雷復卦,夏至後一陰生,配卦為天風姤卦,後天卦用坎一離九,不能配出復姤之卦,且冬至前陰盛極為六陰坤卦,夏至前陽盛極為六陽乾卦,均非坎離之屬,後天坎一艮八震三巽四等四卦,巽卦屬陰,何以配陽局?後天離九坤二兌七乾六等四卦,乾卦屬陽,何以配陰局?故知以後天卦數配局數為非.

(三).歌訣云:甲己居仲上元逢,孟位居中季下宗,五日一元周二遁,十時一甲用皆同;三才變化作三元,八卦分為八遁門;閏奇自有玄妙訣,神仙不肯分明說,甲己二字號符頭,子午卯酉上局設,寅申巳亥中局求,辰戌丑未下局截,萬兩黃金不輕說.

(四).先天八卦以乾兌離震為陽,巽坎艮坤為陰,正好配陰陽局數,故八節配八卦,應為冬至配先天震卦,立春配先天離卦,春分配先天兌卦,立夏配先天乾卦,夏至配先天巽卦,立秋配先天坎卦,秋分配先天艮卦,立冬配先天坤卦,如配六十四卦,冬至配復卦起上元陽一局,頤卦中元陽二局,屯卦下元陽三局,小寒配益卦上元陽四局,中宮中元陽五局,震卦下元陽六局,大寒配噬嗑卦上元陽七局,隨卦中元陽八局,無妄卦下元陽九局.立夏節的芒種氣上中下元陽七八九局配卦大有.夬及乾,夏至氣上中下元陰九八七局配卦姤.大過及鼎.立冬節的大雪氣上中下元陰三二一局配卦比.剝及坤.不論八卦,六十四卦均符合陰陽由初生而至盛極之過程,且完全符合歌訣二至還鄉一九宮之說.
