Purple Star Vs Planetary System (斗数对七政)

紫微斗数和七政四余是中国数术的一种，相信它们是起源于五星论命术。

斗数所使用的大都是虚星大概因为古代中国的天体运算失準和当时的天文学的不盛行有关。虽然虚星的应用，斗数算命也有相当的準确性而拥有不少的拥护者。

七政四余至今还是应用实际的恒星，行星和卫星的位置来计算个人的运程以至择日。相比斗数的盛行，七政论命相对的被冷落；反之西方占星术现在大行其道。东方与西方的占星术是有一些差异的。举例说吧，东方占星在中国用到廿八宿，印度占星只用廿七宿而西方占星就不用。

至于占星和风水的关系是不可分割的。古代的堪舆家吧一个地方的盛衰归咎与天运和地运。地运是通过地盘（九宫飞星）和地形来确定；而地形的吉凶是由‘排龙’来看。而催化地点的运气以达到富贵寿禄的目的，就不得不通过天星择日来造命了。有道：“不得真龙得年月，也应富贵旺人家“是也。可见天体对一地的重要性。

有人把斗数和飞星混合运用美称：”斗数风水“。我个人认为是不靠谱的。虽然斗数和七政是有相同之处；而运用斗数来为阳宅或阴宅造命按宫在理论上是行得通的。但为什么古代的祖师爷不用斗数而用天星来造命呢？

想必实际的星星对现实的世界还是会有影响的。如果用虚无缥缈的星星来催化富贵，所得的东西肯定如‘梦幻泡影’吧。这就是为啥斗数不可以用于阴宅或阳宅的造命了。时师不懂，他的一个无心之失，会使得无辜家庭三代之忧啊！这好比用数术杀人，而杀的是几代的人哦。。

The purple star system and Chinese astrology both are a type of occult sciences that were thought to be originated from the '5 planetary systems'.

The stars used by the purple star system are mainly 'imaginary stars' perhaps because of the lack of advance astronomical calculations in ancient China that caused the calculation of actual planetary positions became inaccurate. So said, though with the employment of 'imaginary stars', the purple star astrology does reasonably accurate in life fortune predictions. Hence, there are many followers of this school.

The old Chinese astrology system which uses the actual positions of stars, planets, sun and moon is not popular and being neglected in this modern times though this astrological system has many uses. On the other hand, the Western Zodiac system became extremely popular nowadays. As the matter of fact, there are some differences between the Eastern and Western astrological systems. For example: the Chinese uses 28 houses to represent the constellation, the Indian uses 27 houses while the Western uses the 12 zodiacs. 

It is often overlooked that the arts of Feng Shui comprised of two elements: the terrestrial and celestial charts. The terrestrial chart refers to the flying star arrangements and the landscapes of an area. The suitability of the area is then determined by the 'dragon arrangement'. Bearing in mind that the terrestrial subjects are passive in nature, i.e. fortune will not come rolling by itself. So, we will need an active element which is the celestial planetary power to activate those hidden energies of wealth, status, sustenance and longevity. 

There is a saying that goes: "Without true dragon but with good timing, fortune should be fallen to people". Hence shows the importance of right timing for energize a place with auspiciousness.

So said, I have recently come across someone advocating the 'Purple Star Feng Shui'. Though it is theoretically not wrong, I cannot second his effort to put such system in place. The question remains: "Why was it that the grand master himself has not replace the imaginary stars with real stars completely?"

This must be true that the real planets still exert some influences to our human world. Please think if imaginary stuffs are used to attract fortune; then the resultant stuffs we get should also of 'imaginary and void' in nature am I not right?

Amateur masters do not care to understand, his one simple seemingly naive mistake will cause three generations' sorrow to an innocent household. What is the difference of killing the entire family then....
