Guru Yantra in Vedic Jyotish is generally used to rectify the negative effects given by Jupiter when it is working negatively in a horoscope. A Guru Yantra is also sometimes used to increase the strength of Jupiter in a horoscope when it is working positively in the horoscope, in order to get more benefits from the positive Jupiter by providing additional strength to it. A Guru Yantra can also bless the native with the things which come under the general significance of Jupiter as well as with the things which come under the specific significance of Jupiter in the horoscope of the native in question. In general, a properly energized and established Jupiter Yantra can bless the native with good results in primary and higher education and it can also at the same time bless the native with financial prosperity as all these fields come under the direct influence of Jupiter.
