Principles of wearing Gemstones
The gemstones are very powerful medium and their effects can be magical as well as very rapid. But this is only possible when these are properly prescribed and are worn by the user in a prescribed manner. Although one can study and learn the use of gemstones from any book or text, but in practice a qualified person should only prescribe the gemstones. Any gemstone when prescribed for a native enhances positively certain aspects of the life but simultaneously gives negative effect on other areas of life also. To understand these pros and cons of any gemstones, one should have proficiency in astrology in addition to the knowledge of the gems and their effects. Only when positive influence of a gem outweighs the negative influence of the gem, it is prescribed.
Sometimes, dynamic prescription of the gems is also done. This system of prescribing gems involves continuous monitoring of the transits of various planets for the native and the changes in Dasas and antardasas of various planets. This is a complicated system and is actually beyond the understanding of persons who are not qualified in astrology. But there are many instances, where it has worked very well for natives over very long periods of time.
