序
任何一门学问。皆深如浩海。学习者多。学精者少。易学之道亦是如此。是故本书命名易学难精。广义泛指世间各种学问。容易学会，难以精通。 而狭义单指易学。易学之中。四柱又最广泛流传。是故本人以四柱为处女作，旨在抛砖引玉。期能引起共鸣。发扬易学。早日还易学本来面目。 四柱预测。实从张果星宗蜕变而来。张果星宗认为人受日月星辰运动而产生命运。
所以用太阳安命，月亮安身，但日月星辰互相影响。运动无周期可言。故身宫无定，独有太阳不受影响，有规律可循。命宫可推，然七十年仍误差一度。二千一百年差一宫(十二地支除三百六十度，一支约三十度。70年乘30度=2100年)此理论是相同四柱而命运不同的最合理的解释。譬如说
癸丑 癸亥 丁巳 甲辰 命宫寅
寅宫共计心、尾、箕三星。查旧版星宗(未知出版年代)此命在尾星四度 新版星宗(清末出版)在尾星十八度
此十四度之差，表示星宗作为一门成熟的学问至少已经历一千年以上(14度乘70年)(清代末年)+（民国与中华人民共和国)，时间远远超过四柱的成熟期(四柱成熟于唐朝，距今只有几百年)，而再经历六百年左右，命宫已经在丑而非寅，不但六亲完全不同，富贵贫贱亦完全不同。所以命宫确实有研究的价值。 虽然本著中之命宫，从四柱的角度来讲，已经细致入微了。但是从星宗的角度来说，仍然是错误的，所以恳请有更高明的朋友不吝赐教。在此表示真诚感谢。
话虽如此，然对四柱的准确性仍有所提高，至少不会误导读者。易友可以放心研究。
