Feng Shui / Astrology

[myfs_81681]

The little I studied about Feng Shui, I understood that there are both universal principals, based on natures influence that affect all individuals in same manner, and relative principals that apply to human beings according to their personal elements, or astrological characteristics. Therefore, an application of Feng Shui may vary according to the person or family who dwells in the house or building. But if we abide by the basic principles of ?good? Feng Shui both to land and house, such as shape of plot, main doors, inclination of land, positive location, absence of negative nearby influences, appropriate Tong Wan, and correct location of rooms, kitchen, bathroom, etc?, could we assume that at least 80 ~ 90% of it?s Feng Shui is good? How important is it to correlate Feng Shui with personal elements. How relevant and important is it to conjugate the astrological study?
