紫微斗数排盘方法考略——定寅首与安星诀辨异

紫微斗数排盘以定寅首、起五行局、安紫微诸星为纲。本文据《紫微斗数全书》与《十八飞星策天紫微斗数》,考其定寅首之法,辨安星诀异同,并附命例以证。

大家好,我是青阳子,学习八字五年。

《紫微斗数全书·安星诀》云:「欲安命宫,先定寅首。寅首者,以生年干起五虎遁,顺数至生月,即得寅宫天干。」此定寅首之总则。然《十八飞星策天紫微斗数》所载「起寅首例」与此略异:其书谓「年干起五虎,正月建寅,顺行十二宫,遇闰月则依节气进退」。两说同源五虎遁,而闰月处理不同。今案:五虎遁本出《渊海子平·论五虎遁》,其诀「甲己之年丙作首,乙庚之岁戊为头」,与斗数定寅首实为一法,唯斗数专用于寅宫起月,子平则用于遁月干。此不可混同。

定寅首后,次起五行局。《紫微斗数全书·定五行局》云:「命宫干支既定,纳音五行即局。水二局、木三局、金四局、土五局、火六局。」此纳音定局法,与《三命通会·论纳音取象》所载纳音五行一致。然《紫微斗数全书》另载「起局例」以命宫天干地支直接查表,不取纳音。两法所得局数偶有出入。如甲子命宫,纳音海中金,为金四局;而查表法亦得金四局,此合。然乙丑命宫,纳音海中金,查表法则作土五局,此异。笔者按:查表法或为后世简化,当以纳音为准,然《十八飞星》用查表法,此流派异说,不可强合。

局数既定,安紫微星。《紫微斗数全书·安紫微星诀》云:「六五四三二,酉午亥辰丑,局数除日数,商数宫前走,若见数无余,便要起虎口,日数小于局,便向宫中守。」此诀以生日除局数,得商数与余数,商数顺行,余数依「酉午亥辰丑」逆布。考其法:日数除局数,商数即紫微所在宫位之基数,余数则定偏移。如金四局,生日初七,七除四得商一余三。商一从寅起一宫至卯,余三依「酉午亥辰丑」从卯逆数三宫:卯、寅、丑,得丑宫安紫微。此与《十八飞星》所载「紫微安星例」小异:《十八飞星》不用「酉午亥辰丑」口诀,而以生日除局数后,商数顺行,余数依「子丑寅卯辰巳午未申酉戌亥」顺数。两法所得紫微宫位不同。如金四局初七,《十八飞星》法得卯宫安紫微,与《全书》法得丑宫异。今案:两法皆传世,当并存待考。

紫微既定,安天府。《紫微斗数全书·安天府星》云:「紫微天府相对宫,紫微在寅天府申,紫微在卯天府未,顺行十二宫。」此以紫微宫位定天府,紫微与天府以寅申为轴相对。如紫微在丑,天府在卯;紫微在子,天府在辰。此与《十八飞星》同。然安十四主星时,《全书》与《十八飞星》所列顺序有别,如天机、太阳、武曲、天同、廉贞等,两书安法互异,此处材料不足,暂不立论。

命例:假设某男,甲子年正月初七日辰时生。定寅首:甲年五虎遁,丙寅起正月,得寅宫天干丙。命宫在寅,干支为丙寅。纳音炉中火,为火六局。生日初七,七除六得商一余一。商一从寅起一宫至卯,余一依「酉午亥辰丑」从卯逆数一宫至寅,得寅宫安紫微。天府在申。余星安法从略。此命例仅示排盘步骤,事应[待补]。

又案:斗数排盘,尚有安身宫、安十二宫、安四化诸节。《紫微斗数全书·安身命例》云:「身宫者,从命宫起,顺数至生时。」与命宫逆数至生时不同。四化则依年干定,如甲年廉贞化禄、破军化权、武曲化科、太阳化忌。此出《紫微斗数全书·四化诀》,与《十八飞星》所载四化表略有出入。学者当以《全书》为宗,参以《十八飞星》,不可执一。

今案:紫微斗数排盘方法,古今流派不一,定寅首、起局、安紫微三节已有异说。若再及安星顺序、四化表,则歧路更多。本文仅就《紫微斗数全书》与《十八飞星策天紫微斗数》互校,列其同异。至若孰是孰非,非有更多古本可证,未敢遽断。存疑待考。

引用书目:《紫微斗数全书》《十八飞星策天紫微斗数》《渊海子平》《三命通会》《神峰通考》。
